Silicon Nitride Ceramic Crucible
Silicon Nitride Ceramic Crucible
Product introduction
1.Silicon nitride ceramic crucible has super hardness and lubricity, so it is very wear-resistant.
2.Almost no reaction with inorganic acid, strong corrosion resistance.
3.resist the influence of cold and heat, and it will not break in the rapid cold and hot environment.
