Ultrapure Silicon Nitride Powder As Refractory Materials

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 composition

3. Low thermal expansion coefficient , high thermal conductivity and strength

4. Good oxidation resistance at high tempereture

Application:

As a new material of modern industry , silicon nitride power is widely applied as 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 can seal the hole of blast furnace wall and be easily cut

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