A vacuum furnace is a type of furnace in which the product in the furnace is surrounded by a vacuum during processing. The absence of air or other gases prevents oxidation, heat loss from the product through convection, and removes a source of contamination. This enables the furnace to heat materials (typically metals and ceramics) to temperatures as high as 3,000 °C (5,432 °F) [1] with select materials.
Vacuum furnaces are used to carry out processes such as annealing, brazing, sintering and heat treatment with high consistency and low contamination. Most vacuum furnace are heated by electric resistance elements made from graphite, ceramics or metals.
Vacuum furnaces are used in many applications in all industries, particularly in the field of superalloy steel production for aerospace, power, automotive and medical as well as advanced ceramics manufacturing.
