<p>The method employs a furnace, wherein organic distillation products released from the binder and the gaseous and particulate decomposition products are burned off. Bodies, placed on the ceramic bottom plate of a truck, are introduced into the pre-heating zone of the furnace, covered with protective coverings, and heated to 200 DEG -600 DEG C. in an oxidizing medium. Thereafter, the coverings are removed in a vestibule, in an inert or slightly reducing medium, and the bodies are introduced into the calcining zone, provided with an inert or slightly reducing medium, to be further heated up to a temperature in the 1000 DEG to 1200 DEG C. range. Lastly, the bodies are cooled in a first cooling zone down to 400 DEG -450 DEG C. in an inert or slightly reducing medium, and in a second zone down to room temperature.</p> |
