Hot Pressed Silicon Carbide



hot pressed silicon carbide overview

Hot pressing, also called pressure assisted densification, a ceramic significantly decreases the defects in the grain structure. This gives hot pressed silicon carbide an extremely hard surface and high-strength which is utilized in ballistic armor.

Example Applications

  • Ballistic armor
  • Etch rings
