High temperature furnaces are another type of laboratory furnace that unlike typical furnaces is capable of reaching higher temperatures between 1400°C up to 1800°C. There are several types of high temp furnaces including
tube furnaces and
box furnaces. A high temp furnace typically consists of heating elements located on both sides of the
heating chamber to ensure good thermal uniformity. Process applications for a high temperature furnace include sintering of high temperature materials, glass melting, high temperature testing of ceramics, fusion and firing processes, and powder metallurgy processes.
