FIELD : chemistry. SUBSTANCE : invention relates to method of obtaining water dispersion of zirconium oxide, which includes interaction of zirconium salt with alkali in water with obtaining suspension of zirconium oxide particles, filtration, washing and re-pulping suspension, addition of organic acid to obtained suspension in amount one mole part or more per mole part of zirconium in suspension, hydrothermal processing of obtained mixture at temperature 170°C and higher for not less than an hour and washing obtained water dispersion of zirconium oxide particles. Invention also relates to method of obtaining water dispersion of zirconium oxide solid solution, which contains, at least, one stabilising element, selected from aluminium, magnesium, titanium and rare earth elements. Invention additionally claimed method of obtaining zirconium oxide dispersion, dispersion medium of which is organic solvent, where claimed method contains replacement of dispersion medium of water dispersion of zirconium oxide, obtained by method, described above, with organic solvent. EFFECT : dispersion of zirconium oxide contains fine particles of zirconium oxide, uniformly dispersed in dispersion medium, and has high transparency. 12 cl, 2 tbl, 1 ex
