Abstract

Способ получения тонкодисперсных порошков на основе диоксида циркония, включающий плазмохимическое разложение его азотнокислых растворов, отличающийся тем, что разложению подвергают коллоидные растворы, получаемые путем введения в азотнокислые растворы циркония шавелевой кислоты из расчета ее содержания в растворах 4,5 - 9,0 г/л с последующей тепловой обработкой растворов в интервале температур 60 - 75С.A method for producing fine powders based on zirconium dioxide, including the plasma-chemical decomposition of its nitric acid solutions, characterized in that colloidal solutions obtained by introducing shavelic acid into nitric acid solutions of zirconium at the rate of its content in solutions of 4.5 - 9.0 g / l are subjected to decomposition followed by heat treatment of solutions in the temperature range 60 - 75C.
