Silicon nitride formula powder
Our company uses different grades of polycrystalline silicon powder as raw materials to directly nitrify and dry process refinement of DN series ceramic grade α-silicon nitride powder. It has high alpha ratio, low impurity content, high degree of crystallization, small particle size (size Can be customized), with excellent molding characteristics and good sintering characteristics, to provide high cost-effective raw materials for the ceramic industry. For customers in the ceramic industry pursuing high performance, our company also provides the JP31A α-silicon nitride powder prepared by the ammonolysis process, which has ultra-low impurity content, high α ratio and extremely high sintering activity. It is a high-end ceramic product. Preferred raw materials.
