Ferrosilicon nitride is an important structural ceramic material. Ferrosilicon nitride is a super-hard substance that is inherently lubricating and wear-resistant. It is an atomic crystal and resists oxidation at high temperatures. Moreover, ferrosilicon nitride can also resist thermal shock. Ferrosilicon nitride can be heated to more than 1000°C in the air and will not break even if it is rapidly cooled or heated again. Precisely because ferrosilicon nitride ceramics have such excellent properties, people often use it to manufacture mechanical components such as bearings, turbine blades, mechanical seal rings, and molds.
ferro silicon nitride powder is applicable to stainless steel smelting, special alloy steel smelting, oriented silicon steel smelting and other casting industries.
As a new type of refractory material, it is applied in the metallurgical field, such as metallurgical furnace body, furnace mouth seal, ironmaking furnace outlet, iron hook amorphous material and nitrogen additive in the steelmaking industry.
Silicon nitride material can be used as abrasive material for abrasive tool manufacturing, and can also be used in chemical fields such as acid resistance, alkali resistance and corrosion resistance.
In terms of steelmaking, granular ferro silicon nitride is mainly used in the production of oriented silicon steel at the initial stage, and it can stably supplement a certain amount of nitrogen for molten steel.
