Ceramic Grade Silicon Nitride Powder

The silicon nitride ceramic powder produced by Sidley Company is synthesized thruough special nitridation process of silicon powder which ensures the powder has high purity, narrow particle size distribution and the products are widely used by many well-known companies at home and abroad. The ceramic structure produced with silicon nitride powder of Sidley has been widely applied in the fields of automotive, aerospace, semiconductor industry, paper industry, mechanical industry, metallurgical industry, petrochemical industry and new energy industries and so on.

Silicon nitride ceramic is known as the “all-around champion” of ceramic materials, a most brilliant jewel in the field of modern ceramic materials. The high-performanceα -type silicon nitride powder of our company is the basic material for preparing high-performance silicon nitride ceramic materials.
