Silicon Nitride Powder Si3N4 Introduction
This organic substance is called Si3N4. This chemical formula is Si3N4. It’s relative molecular masses (RMM) are 140.28. It is available in gray and off-white.
A Pulp Powder of Silicon Nitride si3N4 – Chemical and Physical Properties
Si3N4 exhibits high-temperature insoluble characteristics. It resists high-temperature creep. Hexagonal System. Hexahedral systems crystals have hexagonal structures. The reaction sintering of Si3N4 makes it dense. Si3N4’s density is approximately 1.8 to 2.5 g/cm3. It is density through hot-pressing. Its average density is 3.12-3.22g/cm3. Mohs hardness (99.5), Vickers hardness (2200), microhardness (32220MPa), are all 99.5. This is the 1900 melting temperature (under pressure). It is known as the 1900 melting point under pressure. The specific heat capacity of the material is 0.71J/g*K. The material’s thermal conductivity is 2155 W/(m*K). The linear expansion coefficient is 2.8~3.2×10-6/(20~1000).
It is not soluble in water. It’s insoluble when water. It is at 1300-1400 degrees C that oxygenation occurs in the air. At 500°C the specific volume resistance is 4×108*m. React sintering gives it a compressive force 490MPa. Dicalcium diazide, at 1285 is what forms calcium diazide. At 600 it becomes a transition metal, and is released as nitrogen oxides. The silicon halide’s bending strength is 147 MPa. It can be made by reacting silica hailide and ammonia to silicon powder. It has an ohmic resistance between 1015-1016O.cm. This material can also be used to make high-temperature ceramic materials.
Silicon nitride, other than hot phosphoric or hydrofluoric acid reactions, is extremely resistant to corrosion.

Silicon Nitride Si3N4 Pulverization
Silicon nitride ceramic materials have high thermal stability, oxidation resistance and other benefits. High bond strengths allow for the formation of oxide films within the atmosphere by silicon nitride. It is also very stable chemically. It resists oxidation at lower levels than 1200. Protect it by applying a layer of 12001600. Although silicon nitride doesn’t become infiltrated from lead or aluminum as well silver or nickel, the metal can be affected by magnesium and nickel-chromium alloy.
It is possible to use ceramic materials made out of silicon nitride for these applications
high-temperature engineering components
Advanced Refractory in the metallurgical industry
Materials that are resistant to corrosion
Sealing parts for the chemical, machining and cutting industries.
The strong bonding material of silicon nitride to silicon carbide, silicon dioxide and thoriumoxide is silicon nitride. This can be used to form bonds that permit you to modify the composition.
Also, silicon nitride could be used in
. The PECVD technique is used to cover the silicon-nitride. It can then be used as antireflection material to decrease incident light’s reflections. But, when the silicon-nitride nitride atom reacts with silicon, it enters the silicon wafer and the silicon film. It is an effect of the passivation issue. The ratio of silicon nitride to silicon nitrogen is variable depending on the technological environment. With different properties, there are various atomic proportions.
It is possible to use it in
At ultra-high temperatures, gas turbines and engine engines can be used in conjunction with electric furnaces.
