YSZ METHOD FOR PREPARING YSZ NANO SOL USING SOLVOTHERMAL SYNTHESIS

摘要

(A) preparing a mixed solution by stirring a zirconium acetate solution (ZAS) and a yttrium acetate solution (YAS) at the same concentration with a solvent; (b) adjusting the pH by adding a basic substance to the solution; and (c) heat-treating the solution obtained in the step (b) at a temperature of 120 to 150 ° C to form a yttria-stabilized zirconia , YSZ) nano-sol. The present invention relates to a method for preparing a YSZ nano-sol using a solvent thermo-synthetic method, and more particularly, to a method for producing a uniform high-purity YSZ nano- And the YSZ nano powder prepared according to the present invention can be used for various purposes as a ceramic material requiring high hardness, chemical stability and conductivity.
