| 【Feature】： | With high melting point, good heat resistance, and high resistivity and anti-oxidation. |
| 【Usage】： | Silicon metal powder is widely used in blast furnace refractories, a small number of monolithic refractories for iron runner material or other. |
Silicon metal powder Si3N4 are the main ingredient, along with free iron, not mixture of ferro-silicon nitride and small amounts of other ingredients. Refractories used silicon nitride is a gray-white (or brown) in powder form, Silicon nitride is gray-white granular materials used to make steel. Our silicon nitride are mainly used in refractories, high strength, high temperature, thermal shock resistance, oxidation resistance, wear resistance, good corrosion resistance characteristics, is the first candidate for blast furnace refractories.
