A NEW KIND OF CORUNDUM FIBERS AND SELF-SOLIDIFYING PARTS BASED ON THEM. 1. ANALYSIS OF METHODS OF PRODUCTION OF CORUNDUM FIBERS AND PROSPECTS OF THEIR DEVELOPMENT

摘要

Modern methods of production of corundum fibers with a single-crystal and polycrystalline structure are subjected to a critical analysis It is noted that single-crystal fibers are the most effective but since they are obtained only under laboratory conditions their cost is very high. Four basic methods of production of polycrystalline corundum fibers are discussed. Some substantial disadvantages determining the low output and hence the high cost of the fibers are shown.
