Tetragonal solid solutions based on the TiO₂–CeO₂–ZrO₂ system stable up to 1,350°C were obtained. A method of pH titration of the initial salt mixture was used to study the competitive hydrolysis and precipitation processes in a three-component system. The microstructure and specific surface area of the precursors after synthesis were studied. Adetailed study of precursor phase formation in the range from 600 to 1,350°C was performed using STA, XRD, and laser sedimentography methods. It was shown that for all the studied compositions, an increase in temperature to 1,100°C results in a competitive phase formation accompanied by de-agglomeration in the system up to 1,000°C.

TiO 2 -CeO 2 -ZrO 2系陶瓷前驱体的合成与结构的关系

获得了基于TiO ₂ -CeO ₂ -ZrO ₂体系稳定在1,350°C下的四方固溶体。用pH滴定初始盐混合物的方法来研究三组分体系中竞争性水解和沉淀过程。研究了合成后的前驱体的微观结构和比表面积。使用STA，XRD和激光沉积成像方法对600至1,350°C范围内的前体相形成进行了详细的研究。结果表明，对于所有研究的组合物，温度升高至1100°C都会导致竞争相的形成，并伴随着系统中高达1000°C的解团聚。
