Abstract
1. Способ получения α-окиси алюминия с размером частиц меньше 1 мкм, включающий термообработку, отличающийся тем, что, с целью повышения качества конечного продукта и упрощения процесса, перед термообработкой осуществляют механохимическую активацию гидроксида алюминия при энергонапряженности 1 - 550 Вт/г, а термообработку ведут при температуре 1023 - 1423 К.2. Способ по п.1, отличающийся тем, что в качестве гидроксида алюминия используют бемит, байерит, аморфный гидроксид алюминия, гидраргиллит.1. A method of producing α-alumina with a particle size less than 1 micron, which includes heat treatment, characterized in that, in order to improve the quality of the final product and simplify the process, prior to heat treatment, mechanochemical activation of aluminum hydroxide is performed at an energy density of 1 - 550 W / g, and heat treatment is carried out at a temperature of 1023-1423 K.2. The method according to claim 1, characterized in that boehmite, bayerite, amorphous aluminum hydroxide, hydrargillite are used as aluminum hydroxide.
