BF220-17NH High-Temperature Atmosphere Bell Jar Furnace is a
high-performance and high-precision vertical furnace designed for
elevated temperature processes under controlled atmospheres.
Incorporating advanced design concepts and stringent quality
control standards, it provides an ideal platform for research
institutes, universities, and industrial enterprises to conduct
material sintering, annealing, brazing, crystal growth, and heat
treatment processes in precisely regulated atmosphere environments
and at high temperatures. Its unique bell jar structure not only
ensures user-friendly operation but also guarantees process
consistency and repeatability, making it a key equipment for
advancing new material development and enhancing product quality. 1. Application: It is mainly used in the high-temperature co-sintering process of
alumina substrate and metal slurry (HTCC) in nitrogen-hydrogen
atmosphere.
