<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 (70), placed on the ceramic bottom plate (48) of a truck, are introduced into the pre-heating zone of the furnace (10), covered with protective coverings (58), and heated to 200-600°C in an oxidizing medium. Thereafter, the coverings (58) are removed in a vestibule (16), in an inert or slightly reducing medium, and the bodies (70) are introduced into the calcining zone (18), provided with an inert or slightly reducing medium, to be further heated up to a temperature in the 1000° to 1200 °C range. Lastly, the bodies (70) are cooled in a first cooling zone (20) down to 400-450°C in an inert or slightly reducing medium, and in a second zone down to room temperature.</p> |
