A vacuum furnace is a specialized type of furnace where the product being processed is surrounded by a vacuum.
This creates an environment with no air or other gases, which prevents oxidation, heat loss through convection, and contamination.
Vacuum furnaces are mainly used for processes like annealing, brazing, sintering, and heat treatment.
The primary function of a vacuum furnace is to heat materials, typically metals and ceramics, to very high temperatures.
The maximum furnace temperatures and vacuum levels depend on the melting points and vapor pressures of the materials being heated.
Vacuum furnaces can reach temperatures as high as 3,000 °C (5,432 °F) with select materials.
