Chamber furnaces for oxidizing atmospheres
Chamber furnaces are used for all thermal treatments in air:
- Debinding, sintering;
- Calcination, solid state reactions at high temperatures;
- Melting of glass and metal in crucibles;
Depending on the temperature range, different heating conductors are used:
- up to 1300 °C – FeCrAl (KANTHAL A1) heating conductor;
- up to 1600 °C - SiC-heating rods;
- up to 1720 °C - MoSi2-heating elements;
In addition, the furnaces differ:
- in their usable volume of some ml to 1 m3;
- in the way they are loaded, such as top loading furnace, bottom loading elevator furnace, front loading furnace or hood type furnace;
HTM Reetz GmbH designs and builds chamber furnaces only to customer specifications.
