1. The production volume is different: the diameter of the tube furnace is fixed, and the production volume is relatively small, while the path of the muffle furnace is adjustable, so the production volume is relatively large.
2. Different calcination atmosphere: when the tube furnace is calcinated, it cannot be completely fused with the air, so it is easy to have incomplete calcination, while the muffle furnace can be completely fused with air during the calcination process to make it fully calcined.
