Silicon Nitride Sintering Furnace In Industrial Application Handling Molten Metal
Silicon nitride (SiN) is a non-oxide structural ceramic material that is usually black or dark grey in colour, and often polished to give a smooth and strikingly reflective surface appearance. Popular for its high shock and thermal resistance, its typical applications include metal forming, industrial wear situations and molten metal handling

Facts about Si3N4
There exist three crystallographic structures of silicon nitride (Si3N4), designated as α, β and γ phases.The α and β phases are the most common forms of Si3N4, and can be produced under normal pressure condition. The γ phase can only be synthesized under high pressures and temperatures and has a hardness of 35 GPa.
