Hobersal muffle furnaces are suitable for the ashing process, thanks to their homogeneity and their 4 heating sides they incinerate combustible samples for the final analysis of the residues of the extracted ashes.
Another very important process is calcination, a heat treatment process which by means of high temperature achieves the thermal decomposition of solid materials.
Annealing, another type of heat treatment which consists of the physical alteration of metals to modify their hardness, malleability or ductility.
These 3 processes can be carried out in an oxidising atmosphere (air) or in a modified and/or reduced atmosphere
