Project Description

Silicon Nitride (Si3N4)

Silicon nitride & sialon has the advantages of excellent wear-resistant, heat-resistant,corrosion resistance, non-magnetic and electrical insulation.

It has been proved that silicon nitride & sialon is the best material to alternative zirconia ceramics. And therefore silicon nitride & sialon is applied to more and more fields, such as aluminium industries, polysilicon processing, chemical industry, paper industry, bearing and valve industry,etc.
