Vacuum hot pressing furnace is a vacuum (or other atmosphere) under the conditions of the material hot forming equipment, mainly using resistance or induction heating, driven by the cylinder pressure up and down the pressure. At high temperatures, the solid green particles of the material are interlinked, grain growth, voids (porosity) and grain boundaries are gradually reduced. Through the transfer of matter, the total volume shrinks and the density increases, and finally becomes a kind of microscopic Structure of the dense polycrystalline sintered body, which will press the material forming.
Vacuum hot pressing furnace will be vacuum, atmosphere, hot forming, high temperature sintering together for powder metallurgy, functional ceramics and other new materials, high-temperature thermoforming, such as applied to transparent ceramics, industrial ceramics and other metals and by the composition of refractory metal Vacuum sintering of the alloy material and high temperature sintering of the ceramic material silicon carbide and silicon nitride can also be used for the heat treatment of the powder or compact at a temperature lower than the melting point of the main component in order to improve the strength.
