Sinoma Advanced Nitride Ceramics Co.,Ltd. is subordinate to China National Building Material Group Co., Ltd. (CNBM), is a state-level high-tech enterprise, a state-level "specialized, special and new" small giant enterprise, and a provincial-level gazelle enterprise.

The company has been engaged in the research of silicon nitride ceramics since 1978, and is one of the early research and development units of silicon nitride materials in China, with 78 patents applied for/authorized, and owns independent core technologies including powder synthesis, material preparation and precision processing, with the production and technical strength ranking the domestic advanced level, and the production scale is large, ranking the forefront of the domestic.

The company is the third enterprise in the world to master the mass production technology of hot isostatic silicon nitride ceramic balls, and the products are supplied to global bearing head enterprises (such as SKF, Schaeffler, NSK, NTN, Jtekt, MinebeaMitsumi, etc.), and the performance of the developed high-thermal-conductivity silicon nitride ceramic substrate has reached that of the similar products in Japan.

The company is committed to the research and production of advanced technology ceramics, through the ISO9001, ISO14001, ISO45001 and IATF 16949 management system certification, products to meet the needs of different industrial fields and can provide customers with high-quality solutions.

This position is to develop the silicon nitride ceramic substrate, including the casting, sintering, surface treatment of batch manufacturing technical problems, R&D and design process stability, and quality qualification rate.
