Abstract

Xerogels and powders of a solid solution based on zirconium dioxide are synthesized by the method of coprecipitation of hydroxides from aqueous solutions of salts of zirconium nitrate ZrO(NO₃)₂⋅2H₂O, aluminum Al(NO₃)₃⋅9H₂O, and cerium Ce(NO₃)₃⋅9H₂O with an aqueous 1 M solution of ammonia NH₄OH. A dense ceramic with low porosity and water absorption is obtained. The effect of the ultrasonic treatment of the precipitate and mechanical treatment of the xerogel on the physicochemical properties of the obtained materials is evaluated.

Xerogel 和粉末合成条件对 ZrO_2-СeO_2-Al_2O_3 体系中基于 t-ZrO_2 的陶瓷特性的影响

通过从硝酸锆 ZrO(NO3)2⋅2H2O、铝 Al(NO3)3⋅9H2O 和铈 Ce(NO3)3⋅9H2O 盐的水溶液中与 1 M 的氨 NH4OH 水溶液共沉淀氢氧化物的方法，合成了基于二氧化锆的气凝胶和固溶体粉末。结果得到了一种孔隙率和吸水率都很低的致密陶瓷。对沉淀物的超声波处理和异凝胶的机械处理对所获材料理化性质的影响进行了评估。
