Beryllium and Its Coefficient of Thermal Expansion

Beryllium is a hard gray metal that is naturally found in mineral rocks, coal, and volcanic dust. It can be used to make strong, lightweight alloys. It is also a good neutron moderator and scatterer of high energy neutrons, helping to prevent nuclear reactions and protect the integrity of structures within nuclear reactors. It also has a relatively low melting and boiling point, making it easy to handle and machine.

Like most solids, beryllium expands when it is heated. The amount of expansion is determined by its coefficient of thermal expansion, which is equal to the product of the linear and volumetric thermal expansion factors. A material’s coefficient of thermal expansion is related to its temperature, direction, and pressure. Most materials contract when they are cooled, however, and this is generally referred to as “thermal contraction.”

A simple example of linear thermal expansion is the change in length of a rod that is subjected to a changing temperature. The formula for the change in length is L displaystyle L / d T displaystyle d T, where L displaystyle L represents the initial length of the rod and d T displaystyle d T represents the change in temperature.

Copper beryllium is more resilient than conventional specialty coppers and has a higher elastic modulus. In some electrical devices such as electromechanical relays and switches, these properties allow designers to employ smaller section terminal beam sections than would be possible with other candidate alloys. This results in fewer pieces required to serve the same function, and ultimately reduces unit cost.

The Applications of Stainless Steel 316L Powder

Overview of Stainless Steel 316L Steel Powder
316 stainless steel 316L contains more carbon than 316L. The L is for “low” so this is very easy to remember. 316L does not contain as much carbon but is nearly identical to 316L. The cost is similar and they are both durable and corrosion-resistant. This makes them a popular choice in high-stress environments.
This alloy also contains nickel and chromium. It is more corrosion-resistant than 316L. A 317L alloy, which has an even higher molybdenum percentage than the 316L and 316L, provides even greater resistance to corrosion.
There are many iron-base alloys that contain enough CHROMIUM in order to create a strong passive film.
The qualifying Cr concentration for an alloy called Stainless Steel is 10.5%
The 316L grade stainless steel exhibits excellent corrosion resistance. Metal is stain-proof and non-corrosive as long the invisible or passive film remains intact. Send an inquiry for the most current price if 3D Printing Stainless Steel SS316L Pulp in Bulk.

Common Preparation Methods of Silicon Nitride Powder

What’s silicon nitride?

Silicon nitride can be described as an organic compound with chemical formula Si3N4. It’s a structural ceramic material that is important for its high hardness, intrinsic lubricity and wear resistance. It’s an atomic crystal and is very resistant to oxygenation. Additionally, it is resistant to heat and cold. You can heat it to over 1000 degrees Celsius in air and cool it quickly. Then, you will be able to break the ceramic. This is because silicon nitride pottery has excellent mechanical properties. People use it often to create bearings, blades for turbines, seal rings and permanent molds. The heating surfaces of engine parts can be made from silicon nitride clays which can withstand high temperatures and transfer heat poorly. Not only will this improve engine quality, but also fuel economy and efficiency. Such engines are available in China, Japan, America, Japan, and many other countries.

Silicon nitride preparation method

This is one of the oldest methods for making silicon nitride. In China, it’s still very popular. It is easy and cost-effective. When the iron silicon powder is heated, it reacts with the nitrogen source to create silicon nitride.


This process is cost-effective and requires minimal equipment. But, the metal silicon powder nitridation reaction is exothermic. It is possible for the heat to be trapped in the process of nitriding, but it can cause severe problems. Effects of the nitriding process. The process should be monitored for nitriding temperatures, nitriding speeds, particle sizes, and the concentrations of the diluent. This is because the silicon nitride synthesized in this way has a irregular block shape. Also, silicon nitride powder must be prepared by ball milling and other techniques. It’s not very efficient and easy to add impurities to the product.


Carbothermal reduction is a method to combine SiO2 and carbon under high temperatures. SiO2 can first be reduced to SiO2 in gas phase. Then, SiO2 reacts with nitrogen to make silicon nitride.


To produce solid imino or amino silica, thermal decomposition uses SiCl4 at low temperatures to react with ammonia gases. Both silicicides are easily decomposed at high temperatures to make nitride Silicon. This process has a high rate of reaction and is capable of producing large quantities high-purity silicon powder very quickly. This process is used to prepare silicon powder. It produces a uniform silicon nitride nitride granule with high purity. This is currently the preferred method to commercially produce high-purity silicon nitride powder.

Introduction to Graphite Powder

Where is graphite powder useful? It’s used to make industrial catalysts and chemical fertilizers.
Graphite is a graphite-based lubricant that has high lubricity and resistance to high temperatures.
It is used to release powder metals and as an alloy material, lubricant for cable production, etc.
It can be used for making carbon film resistor, dry mode conductive and preparing conductive coat.
Fillers and performance enhancers can be made for plastics, rubber, rubber-based materials, as well as composite materials. This will improve wear resistance, resistance to pressure, and conductivity.
The marking material of natural graphite is used in ordinary pencils and zinc-carbon batteries. It can also be used to mark motor brushes or other professional purposes.
An innovative application for nuclear-grade graphite are the ultra-high temperatures reactor (UHTR), as well as the next generation of nuclear power plants (NGNP).

What does graphite powder mean?
Graphite Powder is a form of graphite, but it’s only a powder. This retains all its primary and secondary properties.
Graphite, an allotrope carbon, is a form of graphite. It’s grayish-black and opaque. It’s greasy, and it can pollute paper.
It has a hardness of 1-2. The vertical increase in impurities will make it 3-5. Specific gravity ranges from 1.9 to2.3. Its specific surface area concentration is between 1-20m2/g. Under the condition of oxygen isolation, its melting point is above 3000, so it is one of the most temperature-resistant minerals. It conducts electricity and heat.
Not easy to react chemically, has corrosion resistance. Graphite reacts with oxygen to produce carbon dioxide. Strong oxidants, such as potassium permanganate and concentrated nitric Acid can oxidize graphite.
Natural graphite is not pure, so it often contains impurities, such as SiO2, P2O5, CaO, FO, Al2O3, and FeO. They often form quartz, pyrite or carbonate, and can also be found as other minerals. Water, asphalt, H2, CO2, CH4, N2 or other gases are all possible. The analysis of graphite requires that, along with the determination of the fixed carbon contents, volatile matter (ash) must be also determined simultaneously.

Is graphite dust toxic?
Excessive intake of graphite may cause severe damage to the respiratory tract. There have been documented cases of pulmonary fibrosis as well as pneumoconiosis. This is an occupational lung disease. Workers’ lung function and cardiovascular health will be also affected.

How can I substitute graphite powder for
While graphite is a great dry lubricant for aluminum, it can also corrosive when there may be moisture. Graphite is now easily replaced with molybdenum-dioxide MoS2 ().

Application of α Alumina and γ Alumina in the Catalysis of Petroleum Refining

What does alumina mean? Al2O3 is an inorganic compound with the chemical composition. It’s a compound of high hardness with a melting temperature of 2054°C. The boiling point is 2980°C. Alumina for industrial use is made from bauxite (3H2O33H2OO) and diaspore. Chemical methods are used to prepare Al2O3 for high purity. Al2O3 is available in different forms. There are over 10 different types of Al2O3 crystals. There are three types of crystal, which include –Al2O3,-Al2O3 and –Al2O3. There are many differences in the structure, as well as different properties. It is nearly completely transformed at temperatures higher than 1300 into -Al2O3. Use of alumina This is the name of transformer oil. Alumina comes in two main types: type and type. Once the filtrate has been cooled, it is added to an aluminium hydroxide solution crystal, the so-called “Bayer Process”. 1. Al3+, which is found in the lattice for -type aluminium, is evenly distributed within the octahedral coordination centres. This can be broken down in strong acids or strong alkali solutions. After washing, the precipitate is separated, washed and stirred. 2. Alpha alumina cannot be dissolved in water or acid. 9.4, density 3. This is the catalyst carrier and catalyst. Pure alumina, which is a white powder with amorphous properties, can also be used in the manufacture of a variety of refractory bricks. It has a large internal area (a few hundred square meters) and high activity. The bauxite can also be used to make industrial products. These are usually pinkish-coloured or cylindrical, slightly translucent particles. 3. It’s a common adsorbent used in petroleum refining as well as the petrochemical industries. This method is still used for the industrial production of alumina. This enormous amount of lattice energy will result in a completely transformed -type of alumina when it is heated to 1200. 4. -type alumina cannot be dissolved by water. It is sometimes called activated aluminum in the industry. Because of its boiling point and melting point, they are 2980. This means that it can be recycled. KJ Bayer (1888), an Austrian scientist, invented this process. This basic material is used to make metal aluminium. You can reuse it after use by heating the material at 175°C for 6–8 hours. The Bayer process is responsible for over 90% of all alumina worldwide. In the lab, it’s a source of neutral strong deiccants and artificial rubies. Most of the alumina used to produce metal aluminium. TRUNNANO is also known as. Lempotee Nano Technology Co.
