A method of producing polycrystal compound ceramics coating, comprising the steps of: mixing polycrystal compound powder mixture consisting of aluminum oxide spinel 15%-25%, aluminum titanic acid 3%-11%, aluminum cobalt solid solution 17%-24%, aluminum nickel solid solution 3%-8%, silicon 18%-25%, cobalt oxide 4%-10%, ferrosilicon 15%-24%, tantalum carbide 0.2%-2%, manganese oxide 0.05%-2%, silicade molybden 0.3%-6.6% and spinel solid solution 3%-7%, with lithium silicate solution or with silicate line compound solution; mixing the things obtained in the way above with hydroxy compound as a suspension stabilizer or with dispersive silicic acid to obtain suspension; applying the suspension to the surface of metals such as steel plate, stainless steel plate, aluminum plate, copper plate, iron group, platinum group, foundry alloy, refractories, mortar, concrete, fiberboard, and a kind of felt; and hardening and combining them in room temperature and low temperature. The composition can also be used as a moulding by mixing the powder with a binder and calcining, compressing and sintering said mixture. |
