Description:

Silicon nitride powder of gray color is widely applied in steel-smelting, refractory , abrasion rubber , plastic , ceramic and high temperature sealing industries.

Feature:

1. Excellent properties of corrosion resistance thermal conductivity , heat shock resistance and abrasion resistance

2. Good anti-division property and stable chemical comperature.

3. Low thermal expansion coefficient , high conductivity and strength

4. Good oxidation resistance at high temperature

Application:

As a new material of modern industry , silicon nitride powder is widely applied as follows:

1. Non-ferrous metallurgy: Protective coating & film due to its excellent properties of anti-corrosion and non-infiltration.

2. For furnace body or electric furnace , silicon nitride tapping hole clay can seal the hole of blast furnace well and be easily cut

3. As additive of nitrogen during production of alloy steel , especially for producing HRB 400 rebar
