Fɔɔlɔ, metal thermal treatment vacuum furnace sealability is very strict, such as burning the precious stones during the process, so that the color of the precious stones is very bright, to complete sintering in non-oxygen conditions, the process is complicated, second is in the burning process, to repeatedly pump vacuum, because in burning the material will produce other gases, but also to have gas protection, generally can pass nitrogen, hydrogen, argon and other protective gases.
