The invention relates to a method for preparing zirconia precursor sol in one step without concentration. Using basic zirconium carbonate and glacial acetic acid to react, adding yttrium salt crystal phase stabilizer and spinning aid, filtering to remove insoluble impurities, and directly obtaining zirconia precursor sol in one step. The effective components of the obtained sol are polyzirconyl acetate and its crystal phase stabilizer yttrium salt. The preparation of the sol has the characteristics of simple reaction, high zirconium content, uniform and transparent, and easy mixing of various required elements. It can be used repeatedly, and it can be stored uniformly, transparently and without deterioration for a long time. |
