Silicon Nitride Crucibles

Silicon nitride ceramic crucible is made of high purity silicon nitride powder as raw material, mixed with sintering additives, pressed into the shape of a crucible, and then sintered in pressurized nitrogen environment to form a dense structure of silicon nitride ceramic crucible. Silicon nitride crucible is resistant to high temperature, acid and alkali corrosion, also with good thermal shock resistance, it is widely used in high temperature chemical analysis experiments and industrial material testing, used to heat and melt various materials.
