ABSTRACT:
Granular, fire-resistant material, use thereof and process for its production, which process comprises mixing ceramic fibers, a refractory material such as clay, a phosphate bonding agent and water, to form a substantially uniformly dispersed mixture, compacting the mixture by a volume coefficient of at least 3, subjecting the compacted mixture to heat-treatment, and granulating the thus heated product.
