Abstract

A furnace for the thermal treatment, particularly for carbonization and/or graphitization, of material, particularly of fibers, particularly of fibers made from oxidized polyacrylonitrile (PAN), the furnace having a furnace housing and a process chamber located in the interior chamber of the furnace housing, which is delimited by a process chamber housing and into which the material to be treated can be introduced. A process chamber atmosphere prevailing in the process chamber can be heated by means of a heating system. An insulation layer thermally insulates the process chamber. The insulation layer is an insulation fill made from a solid particulate material.
