Powdered ferrosilicon nitride is mainly used in the plugging mud of large blast furnaces, and a small amount is used in iron channel materials or other unshaped refractory materials; granular ferrosilicon nitride is mainly used in oriented silicon steel or other materials that use nitrides to improve strength steel type.
