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.
Primary variables defining a powder sintering operation are time, temperature and furnace atmosphere. Sintering temperature is typically .7 to .9 of the powder's melting point. Sintering time is dependent on manufacturing process factors and material. Tungsten, for example, is sintered for a relatively long time.
Sintering of binderless tungsten carbide - ScienceDirect . The activation energy is lowered for nano-scale powders, and hence a low sintering temperature is needed, and cemented carbide with better physical and mechanical properties can be obtained, .

95% nitrogen (N 2) mixed with 5% hydrogen (H 2) gases was used as sintering atmosphere in a tube furnace whereas vacuum atmosphere was carried out in vacuum furnace. The sintering process was
Tungsten sintering, in practice, is always performed in reducing atmosphere which removes the oxygen coating of the powder particle surfaces. High-purity dry hydrogen is commonly used. Under vacuum or in inert gas, sintering is retained by residual oxygen, and the desired density will not be achieved.
