P5 Vacuum Hot-Pressing Sintering Furnace

Vacuum Hot-Pressing Sintering Furnace combines vacuum/atmosphere, hot press forming and high temperature sintering, suitable for high temperature thermoforming of new materials such as powder metallurgy and functional ceramics, such as applied to the transparent ceramics, industrial ceramics, and alloys composed of refractory metals. Vacuum sintering of materials and high temperature sintering of ceramic materials such as silicon carbide and silicon nitride, can also be used for heat treatment of powders or compacts at temperatures below the melting point of the main components, with the aim of increasing the strength by metallurgical bonding between the particles.
