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

Features:

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

2. Good anti-division property and stable chemica composition

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

Iron & steel smelting:

1. In steel industry , silicon nitride coating can efficiently solve the oxidation loss of billet during heat-treatment process

2. For furnace body or electric furnace , silicon nitride tapping hole caly 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
