Abstract

Способ получения нанодисперсного порошка оксида циркония, стабилизированного оксидами иттрия и/или скандия, включающий получение исходной смеси нитратов соответствующих металлов и глицина, нагревание смеси до температуры 160-250°С и выдержку при этой температуре с последующим отжигом, отличающийся тем, что в исходную смесь дополнительно вводят карбоновую кислоту и/или аммонийной соли карбоновой кислоты или аминоуксусной кислоты в количестве 5-20 масс.% от содержания глицина и отжиг осуществляют при температуре 550-570°С.A method of obtaining a nanosized powder of zirconium oxide stabilized by yttrium and / or scandium oxides, comprising obtaining an initial mixture of nitrates of the corresponding metals and glycine, heating the mixture to a temperature of 160-250 ° C and holding at this temperature, followed by annealing, characterized in that in the initial mixture additionally, carboxylic acid and / or ammonium salt of carboxylic acid or aminoacetic acid are introduced in an amount of 5-20 wt.% of the glycine content and annealing is carried out at a temperature of 550-570 ° C.
