Abstract

Hydrated zirconia was obtained by solid state synthesis and precipitation. Physicochemical properties and phase composition of calcined hydrated zirconia was investigated by XRD, IR and DSC-TG. Hydrated zirconia obtained by solid state synthesis has lower moisture content and higher filterability to compare with precipitated one. Zirconia precursor synthesis with ammonium carbonate considerable decrease specific surface area to compare with precursor precipitated by ammonium hydroxide or ammonia. Tetragonal and monoclinic zirconia was obtained by hydrated zirconia calcination under 450 °C. Calcination temperature increase up to 600 °C lead to drastically decrease of tetragonal zirconia content. The roast obtained under 1150 °C contain only monoclinic zirconia.
