Si3N4 powder is also known as silicon nitride. Silicon nitride has super-hard properties and is resistant both to wear and high temperature oxidation. Purity: 99%
Particle Size: 0.25um-1.50um
The silicon nitride composition It is made of silicon and nitrogen. Si3n4 in silicon nitride has the highest thermodynamic stability. It is a solid white color with high melting points, chemical inertity, and can also be used to diluted H2SO4 or HF. It is extremely hard, 8.5 on Mohs scale. This makes it very stable and thermally stable.
Silicon nitride An inorganic substance is one that can be found in the silicon nitride formula It is also known as Si3N4. It’s a key structural ceramic material that has high hardness and wear resistance.
Conductivity thermal of Silicon Nitride The value is 17.4423.26W/m* (0 1,000). Furthermore, the material can withstand extreme cold temperatures up to 1000 degrees C, as well as sharp cooling, heating and subsequent cooling. It’s precise, because silicon nitride ceramic Because of their excellent properties, people use them often to create mechanical components like bearings, blades for air turbines, seals, or permanent molds. If Si3n4 silicon nitride clay These are highly resistant to heat and can not be easily transferred. It is possible to improve the heat-inspiration layer of the engine component, which not only increases the quality but also fuel efficiency.
Silicon nitride can be difficult to manufacture as a bulk material. It cannot be heated to more than 1850°C. This is due to the dissociation of silicon and nitrogen. It is therefore difficult to use hot press sintering. The temperature at which silicon nitride can be bonded to each other is lower. Alternatives include spark plasma sintering, which involves rapid heating (in seconds) using pulses or electric current to compact the powder. At temperatures of 1500 to 1700°C, this method has produced dense silicon nitride-compacts.

The Chemical Composition Of Silicon Nitride Si3N4 Puffer:
It is simple. Silicon Nitride Si3N4 Powder produced?
It can perform direct silicon nitride or nitrogen extraction using the hexagonal bSi3N4. This can be done at a temperature of between 100 and 1400 C.
SiCL4 (L), 6 NH3(g) – SI (NH) 2 (+4 NH4Cl) (S), under conditions of zero degrees Celsius
3 Si (NH2)2 (Si3N4 (Si3N4) (S + N2(g) + H2 (g), at 1000 C
You could also try a carbon thermo reduction reaction in a Nitro atmosphere at 1400-1450°C under a Nitro atmosphere.
3 SiO2(S)+ 6 C (+ 2 N2 [g] – Si3N4S] + 6 CO (6 CO (g).
But, silicon nitride made from impurity iron or silicate will be produced depending on the quality of silicon raw materials. It is important to note that silicon nitride is not amorphous when it has been synthesized through diamine degradation. There is a commercially-available method of producing silicon nitride. Carbon-thermal reduction is the best way to create silicon nitride. This also makes it the most economically-friendly method of producing silicon powder in industry.
This is chemical vapor vapor or plasma enhanced chemical vapour deposition technique that creates the silicon nitride films at electron level.
3 SiH4 (G) + 4 NH3 (g) – Si3N4 (S) + 12 H2 (g)
3 SiCL4 / G + 4 NH3 g – SI3N4 (S) +12 HCl g
3 SiCL2H2 g + 4 NH3 g – SI3N4 s) + 6HCl g + 6 H2 g
You can deposit money if you wish. Silicium Nitride is used on semiconductor substrates Two methods are available:
Horizontal or vertical tube furnaces can be performed at very high temperatures by using low pressure chemical vapor deposition methods.
Plasma enhanced chemicalvapor deposition methods are performed at relatively low temperatures and in vacuum.
Silicon nitride cell parameters are quite different to single-textile silicon. Also, deposition methods can affect the generation of silicon nitride. silicon nitride film Stress can cause tension and stress. Tension can be reduced when used with plasma-enhanced vapor deposition methods.
Silica was first prepared using soluble gel. Next, the silicon nanowires had to be treated with silica Gel. Silica gel contains special carbon particles that are made of glucose at between 1200 and 1350°C.
