Non-pressure Furnace
High Temperature Non-pressure Furnace, 1600℃ 10pa Vacuum Furnace for Si3N4 Powder
Non-pressure atmosphere furnace is equipped with Vacuum System, when the air in the chamber pumped out, inlet high purity N2 into the chamber, and sintering under the N2 protective environment. When used for the production of high purity Si3N4 powder, the N2 and Si powder can fully react, the flour extraction rate can reach 92%.

- Ceramic Fiber Chamber, Mosi2 heating element, max. temperature can be 1600℃
- Can realize multi-zone temperature control as per heating zone length, make sure the temperature uniformity of the working chamber.
- Chamber bottom adopts high strength alumina brick, with loading car rail, can easily load sintering material.
- Double-pole rotary mechanical pump, the vacuum can be 10Pa.
- Special gas circuit design, High purity N2 inlet into the chamber through the gas circuit after deoxidation and dewatering treatment, exhaust at the release port of chamber, thus ensure N2 can circuit effectively.
- Sliding furnace tank design, can maintenance conveniently.
Optional Spares:
- Si3N4 loading box
- Si3N4 protection board
