Ceramic Grade Silicon Nitride Powder

 

Silicon nitride (Si3N4) is off-white, a synthetic covalent compound, and high-performance inorganic non-metallic material. Silicon nitride ceramic materials or silicon nitride refractory materials have excellent physical and chemical properties, such as high hardness, wear resistance, great modulus of elasticity, high strength, high temperature resistance, oxidation resistance, high thermal conductivity, low thermal expansion coefficient, low density, small specific gravity, excellent resistance to corrosion of acids, alkali and molten metal, excellent thermal stability and electrical insulating properties.

Aspects of Silicon Nitride Ceramic

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-performance╬▒ -type silicon nitride powder of our company is the basic material for preparing high-performance silicon nitride ceramic materials.

With the rapid development of technology, there is an urgent need for materials with high-temperature resistance, high hardness, high strength, and resistance to corrosion. After long-term efforts, silicon nitride was not taken seriously until 1955. In the the mid-seventies, silicon nitride ceramics were really produced with high quality, low cost, and a wide range of important uses. The performance and functionality between silicon nitride powder and silicon nitride ceramic products are very different. Without strict and elaborate re-processing on silicon nitride powder, it is impossible to get the silicon nitride ceramic products with excellent properties. The  ceramic grade silicon nitride powder produced by our company fully meet the quality requirements of the production of silicon nitride ceramics.

Other Aspects

As a new modern industrial material, silicon nitride powder also has a very wide range of applications in non-ferrous metals, rubber, plastics, wear-resistant materials, the defense industry, electronic industry and other fields
