摘要：
A fluidized bed reaction pipe (1) made of sintered silicium carbide has a fritted plate (2) made of silicium nitride or carbide. The fritted plate is preferably sintered together from individual, preferably spheric, sintered silicium nitride bodies. The reaction pipe is characterized by good thermal and thermal change resistances and is suitable for carrying out reactions at up to 1650 DEG C. Also disclosed is a process for high temperature treatment of corundum micro-grains in the fluidized bed which can be carried out without the admixture of coarse grains and which supplies an agglomerate-free product.
