Products Description

2000℃、1900℃ 1800℃ Argon Graphite Heating Vacuum Furnace For Sintering Zirconia Nano Graphene Activated Carbon Materials.

The vacuum furnace is a high temperature, high vacuum resistance furnace using graphite as a heating element. The maximum working temperature can reach 2000 °C ~ 2200 °C. This series of products are widely used in inorganic materials (such as ceramic seals, silicon carbide, zirconia, zinc oxide, alumina, etc.), and metal materials (such as cemented carbide) sintered in a vacuum or protective atmosphere, can also be used Purification of rare earth elements and their oxides and sapphire annealing treatment. It is also suitable for use in colleges and universities and research institutes for pilot production.
