Silicon Nitride Crucible Applications

  • Metallurgy: Si3N4 crucibles are used for melting and casting metals and alloys that require high temperatures, such as titanium, nickel-based superalloys, and certain advanced aluminum alloys.
  • Advanced Ceramics Production: In the manufacturing of ceramics, these crucibles are used for sintering, firing, and melting processes that involve high temperatures and require materials that do not react with the ceramics.
  • Chemical Analysis: Silicon nitride crucibles are utilized in laboratories for conducting high-temperature chemical analyses and experiments where contamination must be avoided.
  • Semiconductor Industry: They may be used in processes that require high purity and resistance to thermal shock, such as the growth of semiconductor crystals.
