Silicon powder can be used as an organic non-metallic inorganic nontoxic and odorless material. It is highly insulation and resistant to acid, alkali, corrosion. Purity(%): >99.95 APS(nm) Silicon powder Silicon fume also known by microsilicon is an industrial process that smelts industrial silicon in an electric furnace at high temperature. Special collection devices are used to collect the dust and smoke that is released with the exhaust gas. Become. silicon powder has the scientific name “micro silicon” or “silicon”. It is produced by high-temperature smelting industrial silicon and ferrosilicon using an industrial electric furnace. Special traps are used to collect the exhaust fumes and dirt. About 90% of total dust and smoke emitted from exhaust gas is SiO2. The particle size of silicon powder is small. It is also very tiny. Silicon 0_ is an organic non-metallic inorganic material that’s non-toxic and odorless. It has excellent temperature resistance, alkali and acid corrosion resistance, high frequency coefficient, high insulation and low expansion. pure Silicon powder can be used widely in chemical, electronics and integrated circuits. With a concentration of 277,000ppm, silicon, second only to carbon, is the most abundant element. It is usually found as silicate which can be found in many soils, clays, rocks and other materials. By combining silicon dioxide (sand or SiO 2) and carbon, you can obtain Silicon. By using zone refining components that are used for high-purity purposes (such semiconductor devices), they can be further purified and their purity improved to better than 1:109. There are two types of silicon. While brown silicon can be considered a powder or metal, the white crystalline (or metallic) version of silicon is far more popular. Lump silicon does not react with water, oxygen or acids (except HF), however it can be dissolved in hot alkali. Silicon can be used in many industries. Due to its unique semiconductor properties, the semiconductor industry uses ultra-high purity silica. Some alloys also use silicon as an alloying element, like ferrosilicon (an alloy of iron with silicon that is used to add silicon to steel and cast Iron). It can also be used for glass production. The morphology and structure of elemental silica includes monocrystalline Silicon, and Amorphous Silicon. If you are interested in buying silicon powder bulk, please send us an inquiry. Silicon Si Si powder CAS 7440-21-3 Descriptions of Nano Silicon Powder nano silicon powder APS(nm): 2-1000nm nano silicon powder Purity(%): >99.95 Nanosilicon powder Specific surface area(m2/g: 60 nano silicon powder Volume density(g/cm3): 0.09 nano silicon powder Density(g/cm3): 2.3 nano silicon powder Crystal form: Sphere Colour: Yellow nano silicon powder CAS No. : 7440-21-3 nano silicon powder EINECS No. : 231-130-8 Silicon powder performance It is high in purity. The scattered performance is excellent, and the particle size small. Because of the large surface area and low density, pine installations the activeness is good as well as good characteristics. A nanometer-sized silicon can be combined with graphite to make lithium battery’s cathode materials. It may also include a nanometer titanium tube or nanometer carbon nanometer tubes. These compounds may improve lithium battery’s performance and service life. The new generation electro-optic semiconductor material has the large gap energy. How Silicon Si granule is produced? Reducing quartzite and sand with high purity coke produces silicon that is 96-99% pure. In an electric arc furnace, the reduction occurs. Any excess SiO2 can be used to keep the silicon carbide (SiC), from accumulating. SiO 2 + 2 C→Si + 2 CO 2 SiC + SiO 2 →3 Si + 2 CO This is known as the carbothermal removal of silicon dioxide. It’s usually done in the presence of scrap ferrous iron. The scrap iron contains small amounts of sulfur and phosphorous, and forms ferrosilicon. Ferrosilicon (iron-silicon alloy) is a mixture of iron and silicon that contains different levels of elemental iron. It accounts for approximately 80% world elemental Silicon production. Ferrosilicon can be found in the steel industry. This alloy is used primarily as an additive to iron and steel. As shown below, another possible reaction is called thermite-reduction of silica. 3 SiO 2 + 4 Al→3 Si + 2 Al 2 O 3 The chemical industry can use 98.5% of pure silicon produced by leaching 97-97% of the powdered silicon with water. To achieve higher purity for semiconductor applications however, it is necessary to reduce tetrachlorosilane or trichlorosilane. While the first is produced by chlorinating waste silicone, the second is an by-product from organic silicon production. Because these compounds are volatile they can be removed by multiple fractional distillation. They then become elemental silicon when reduced with very pure zinc as a reducing agent. This produces sponge-like silicon wafers that are meltable and can then be grown into single crystals. These are then further refined using zones. Silane or Tetraiodosilane can also be used (SiI4). An alternative method to reduce sodium fluorosilicate is to use metallic sodium, which is a commonly used waste product of the phosphoric acids fertilizer industry. It is exothermic so it does not require any external fuel. Ultra-fine Silicon has a greater purity than other materials. In order to produce transistors, it is necessary that the impurity of silicon crystals be lower than 10 percent in 10 1 parts. Also, if you are obtaining ultra-fine silicon under certain circumstances, then the impurity content must not exceed 12 percent in 101 parts. Application o Silicon Si powder HTML3_ : Finely processing silicon powder involves crushing, grinding and grading. The powder has a high purity, excellent particle gradation and clear color. Silica fume, an effective active admixture that can dramatically improve concrete’s strength, impermeability and frost resistance, is a great choice. Silica fume concrete has attracted attention due to its unique properties. This concrete can be used for water conservancy, hydropower engineering construction engineering highway engineering bridge engineering. (1) High insulation: Because of the purity and stability of the silicon powder, as well as the excellent electrical insulation the product cures, it is able to provide good insulation and resistance to arc. (2) The exothermic peak temperature for the curing of epoxy resin can be reduced, the linear expansion coefficient and shrinkage rates of the cured products can also be decreased. This reduces the internal stress in the product and helps to prevent cracking. (3) It is resistant to corrosion. Silica powder doesn’t react well with many acids or alkalis, so it is difficult for other substances to react. Because its particles are evenly covered with the object’s surface it is strong in resisting corrosion. (4) A reasonable particle gradation allows for the reduction and elimination of precipitation and delamination in use. This can improve wear resistance, tensile strength, compressive strength, thermal conductivity, as well as the product’s resistance to heat. Combustion performance. Silane coupling agents are used to make silica powder. They have good wettability, excellent adsorption, no agglomeration, and easy mixing. Sixth, Silica powder can be used to fill the organic resin. This not only increases the product’s performance but also lowers its cost. Storage Conditions for Silicon Powder It is important to keep this product in a dry, cool environment.
