摘要：
We show a feasibility of preparing a highly homogeneous composite gel (CG) based on hydrolysis products of Al2O3-ZrO2 salts. The phase composition of a sample calcined at 1250°C for 2 h is as follows: α-Al2O3, t-ZrO2, and m-ZrO2 where the t-ZrO2/m-ZrO2 phase ratio ranges from 2.8 to 3.8 depending on gel preparation conditions. The investigative tools used are powder X-ray diffraction, differential thermal analysis (atmosphere: Ar), and IR spectroscopy.
