Silicon nitride is a material characterized by a strong covalent bond structure, showcasing outstanding comprehensive properties across a temperature range of -200°C to 1600°C. These remarkable properties encompass high strength, hardness, high thermal conductivity, high temperature resistance, wear resistance, corrosion resistance, oxidation resistance, good fracture toughness, exceptional thermal and mechanical shock resistance, and more. Such a combination of attributes distinguishes silicon nitride as the unparalleled "all-around champion" in the realm of ceramic materials.

The CF-1A powder produced by our company is used as the critical material for the production of silicon nitride ceramic structural parts. CF-1A utilizes high-purity silicon powder as its raw material and is prepared through a direct nitriding process. This product has several advantages, including a high a phase content, a narrow particle size distribution, and high sintering activity. making it suitable for diverse processes and applications involving silicon nitride ceramics.
