Pressureless sintered silicon carbide (SSiC) is a ceramic material that is produced by sintering silicon carbide powder without the use of any external pressure. Sintering is a process in which ceramic particles are heated to a high temperature, causing them to bond together and form a solid mass.

  SSiC is known for its excellent mechanical properties, including high hardness, high strength, and high wear resistance. It also has good thermal conductivity and low thermal expansion, making it suitable for applications in high-temperature environments.

  The pressureless sintering process allows for the production of complex shapes and large parts, making SSiC a versatile material for various applications. It is commonly used in industries such as aerospace, automotive, semiconductor, and chemical processing.

  Some typical applications of pressureless sintered silicon carbide include mechanical seals, bearings, nozzles, valves, and cutting tools. Its superior mechanical and thermal properties make it an ideal choice for demanding and high-performance applications.
