Graphite furnaces
The term graphite furnaces covers all furnaces with one common feature: at least the heating conductor and usually also the insulation are made of graphite.
Graphite furnace – up to 3000 °C
The highest temperatures are achieved with this material, and the heated room can take a wide variety of forms. These furnaces are often used for heat treatments in inert atmospheres.
