This new material sintering furnace equipment uses graphite as a heating element for heating or medium frequency induction heating. The maximum working temperature can reach 2400℃~2600℃. This product is widely used in the sintering preparation of inorganic materials (such as ceramic seals, silicon carbide, zirconia, zinc oxide, aluminum dioxide, etc.) and metallic materials (such as cemented carbide) in vacuum or protective atmosphere. It can also be used for rare earth materials. Purification of elements and their oxides and sapphire annealing. At the same time, it is also suitable for use in pilot batch production by colleges and universities and scientific research units.
