High Purity Silicon Nitride Powder For Tapping Hole

We are one of the well known companies engaged in exporting, distributing and supplying a wide range of High Purity Silicon Nitride Powder for tapping hole in Zibo, Shandong Sheng, China. We source these powders from the reliable vendor in the industry. 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 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.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 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
