# Vacuum Sintering Furnace

Vacuum sintering, refers to the process that making the powder material into dense material in the condition of the vacuum.People use this process to produce ceramics, powder metallurgy, refractories, ultra-high temperature materials.
In general, after forming the powder and by the sintering process, it becomes the density mateiral.The sintering process directly affects the grain size, pore size and grain boundary shape and distribution in the microstructure, thus affecting the properties of the material.
