Beijing Sinoma Synthetic Crystals Co., Ltd. is subjected to China National Materials Group Corporation (SINOMA). Our company is engaged in researching, manufacturing and developing synthetic crystals, high performance ceramics and advanced functional composites.

Department of Advanced Ceramics of our company has carried on researches in the fields of oxide ceramics, nitride ceramics, carbide ceramics, fluoride ceramics, sulfide ceramics and ceramic-based compound materials since the 1970s and has developed items of proprietary technologies with our own intellectual property. Our main industry of the department is developing and manufacturing such advanced ceramic materials and the interrelated products as silicon nitride, alumina, zirconia and others. Our products are broadly sold to the developed countries such as Sweden, America and Japan.

Products developed and manufactured by the department such as full-ceramic bearings, mixed-ceramic bearings, ceramic balls, silicon nitride gasket seals for boilers, silicon nitride based ceramic tubes used for chromoscope glass shells, abrasion resistance sealing elements used in chemical industry, all kinds of irregular silicon nitride products, alumina ceramics, and zirconia ceramics, are being widely used in fields of aviation, aerospace, basic industry, and national defense.

Among all the products, silicon nitride ceramic bearing balls and silicon nitride based ceramic tubes used for chromoscope glass shells have been appraised as "Fangles of the State". Additionally, Beijing Sinoma Synthetic Crystals Co., Ltd. enjoys eight patents for invention in nitride ceramics.
