Claims (1)

Способ получения диоксида циркония из оксихлоридных растворов путем электрохимической и термической обработки, отличающийся тем, что раствор оксихлорида циркония подвергают электрохимической обработке в катодной камере трехкамерного электролизера, в котором средняя камера отделена от катодной анионобменной, а от анодной - катионообменной мембранами, при плотности тока 0,5 - 10,0 А/дм2 и рН католита = 2,0 - 2,8, при этом среднюю камеру первоначально заполняют дистиллированной водой, а анодную - 1 - 5% раствором кислородсодержащей кислоты.A method of producing zirconium dioxide from oxychloride solutions by electrochemical and heat treatment, characterized in that the zirconium oxychloride solution is subjected to electrochemical treatment in the cathode chamber of a three-chamber electrolyzer, in which the middle chamber is separated from the cathode anion exchange, and from the anode chamber by cation exchange membranes, at a current density of 0, 5 - 10.0 A / dm 2 and catholyte pH = 2.0 - 2.8, while the middle chamber is initially filled with distilled water, and the anode chamber with 1 - 5% solution of oxygen-containing acid.
