Vacuum pressure sintering furnace

The vacuum pressure high-temperature sintering furnace uses high-purity graphite as the heating element, WRe thermocouple as the temperature measuring element, and a precision digital program temperature controller to control the temperature, which can achieve automatic program temperature rise and fall of the furnace. The furnace can be evacuated by a secondary vacuum unit to achieve vacuum sintering of samples, and a protective atmosphere or reaction atmosphere can also be injected for high-pressure high-temperature sintering. The equipment is widely used in sintering tests of structural ceramics, functional ceramics, hard alloys, bioceramics, artificial crystals, composite materials, etc.
