    摘要: Low-soda alumina granules suitable for use as an alumina porcelain insulator and alumina catalyst carrier, and the method and equipment for their manufacture. The method comprises dehydrating aluminum hydroxide at a high temperature and then granulating it. The granules thus obtained are placed in an autoclave, washed and cured with water drops, then taken out of the autoclave dried and fired. The manufacturing equipment is used for curing the granules with water drops.
