Abstract

Xerogels in the ZrO₂–Y₂O₃–CeO₂ system are obtained by coprecipitation. The influence of the synthesis method on the acid-base xerogel surface properties are studied. The sinuous dependence of the Lewis and Brønsted site content on the particle surface on the conditioning time of precipitates in the mother liquor and the presence of subsequent low-temperature processing is established. The relationship is established between the resulting ceramics properties, precipitate processing conditions, and the functional xerogel structure.

ZrO 2 -Y 2 O 3 -CeO 2体系干凝胶合成条件对基于它们的粉末和陶瓷性能的影响

摘要

通过共沉淀获得ZrO ₂ -Y ₂ O ₃ -CeO ₂系统中的干凝胶。研究了合成方法对酸碱干凝胶表面性能的影响。确定了颗粒表面上路易斯和布朗斯台德位点含量对母液中沉淀物的调节时间的曲折依赖性，并确定了随后进行的低温处理。在所得陶瓷性能，沉淀物加工条件和功能干凝胶结构之间建立了关系。
