Uses of calcium borate in various fields


A calcium borate ceramic powder comprising the following steps: uniformly mixing and drying calcium oxide and boron powder and placing them in a high-temperature reaction furnace; Conducting vacuum treatment before heating treatment in the high-temperature reaction furnace; Reacting calcium oxide and boron powder at high temperature under vacuum and inert gas protection; Separating and purifying calcium hexaboride ceramic powder; The separated and purified calcium hexaboride ceramic powder is subjected to ball milling treatment to obtain uniformly dispersed calcium hexaboride ceramic powder. The method of the invention is simple, easy to implement, and has low manufacturing costs. The prepared calcium hexaboride ceramic powder has small particles and uniform dispersion. To prepare a ladle gunning material with calcium borate added, the ladle gunning material comprises the following components by weight: 25 to 52 parts of magnesia with a particle size of 0>1 mm, 25 to 52 pieces of magnesia with a particle size of 1>3 mm, 18 to 28 pieces of magnesia with a particle size of 200 mesh, 1 to 2 parts of calcium borate, and CA? Fifty cement 0.5 to 5 pieces, bentonite 0.5 to 5 parts, sodium silicate 1 to 8 parts, modified asphalt 0.5 to 7 domains. The ladle gunning material prepared by the invention has good oxidation and peeling resistance. It has good fluidity and long service life, making it more suitable for large-scale ladle use. The preparation of a rotary kiln refractory material comprises the following parts by weight of raw materials: 70 to 80 parts by weight of bauxite, 1 to 3 parts by weight of aluminum silicate fiber, 6 to 8 parts by weight of silicon dioxide, 3 to 6 parts by weight of calcium hexaboride, 8 to 10 parts by weight of water, and 6 to 12 parts by weight of zirconium nitride.
