Brief introduction：
Silicon nitride is an important structural ceramic material. It is a super hard substance, lubricity in itself, and wear - resistant, for atomic crystals; Oxidation resistance at high temperature If the heating surface of engine parts is made of si3N4 ceramic which is resistant to high temperature and difficult to heat transfer, the quality of diesel engine can be improved, fuel can be saved and thermal efficiency can be improved.
* As a new profile in modern industry, si3n4 powder is widely used in ceramic refractory steel, metallurgy and non-ferrous rubber industry.
* In the nonferrous industry, its corrosion resistance and erosion performance is very excellent, widely used.
*The experimental results show that the anti-oxidation effect of nano-silicate anti-oxidation coating is obvious, which can reduce the oxide scale of 3%-5% produced by ordinary hot rolled plate to 0.1-0.8%, and reduce the oxide scale of 1%-3% produced by stainless steel hot rolled plate to 0.2%.
