2025 Factory Price Ferrosilicon Nitride

Silicon nitride is a metal alloy mainly composed of a mixture of Fe and Si3N4, which has superior properties such as high temperature resistance, oxidation resistance, and corrosion resistance. It can be used as an additive in refractory materials to improve its overall performance.

1.High melting point and thermal stability

Silicon nitride iron is resistant to high temperatures (usually up to 1200 ° C or above), has strong oxidation resistance, and is suitable for use in high-temperature environments.

2.Wear resistance and hardness

Due to the presence of silicon nitride, it has high hardness and excellent wear resistance.

3.Chemical inertness

Has good resistance to acids, bases, and molten metals.

Good sintering performance

Can be used as an additive to improve the sintering performance of ceramics or refractory materials.

1-Metallurgical Industry

Steelmaking additive: As a nitrogen source and alloying element, it improves the strength of steel (such as producing high nitrogen steel).

Cast iron modifier: improves the wear resistance and corrosion resistance of cast iron.

2-refractory material

Used for high-temperature components such as steel ladles and blast furnace linings to enhance thermal shock resistance and slag erosion resistance.

3-Ceramics and Composite Materials

As a reinforcing phase, it enhances the fracture toughness and high-temperature performance of ceramics.

4-Wear resistant coating

Used for spraying or sintering coatings to protect mechanical components from wear and tear.
