Abstract

The phase composition, microstructure and ceramic properties of zirconium dioxide containing yttrium oxide (2.5 mol %) and aluminum oxide (10 wt %) depending on the amount of lithium-containing additive were studied. It was found that the introduction of a lithium-containing additive leads to the formation of a lithium aluminate phase and an increase in the content of the monoclinic modification of ZrO₂. Sintered materials were obtained at 1450°C, characterized by an open porosity of less than 0.5%.

含锂添加剂对ZrO2-Y2O3-Al2O3体系材料微观结构、相组成及性能的影响

研究了含氧化钇（2.5 mol %）和氧化铝（10 wt %）的二氧化锆的相组成、微观结构和陶瓷性能随含锂添加剂用量的变化。结果表明，引入含锂添加剂可导致铝酸锂相的形成和ZrO2单斜改性含量的增加。在1450℃下得到烧结材料，其特点是孔隙率小于0.5%。

期刊介绍： Inorganic Materials is a journal that publishes reviews and original articles devoted to chemistry, physics, and applications of various inorganic materials including high-purity substances and materials. The journal discusses phase equilibria, including P–T–X diagrams, and the fundamentals of inorganic materials science, which determines preparatory conditions for compounds of various compositions with specified deviations from stoichiometry. Inorganic Materials is a multidisciplinary journal covering all classes of inorganic materials. The journal welcomes manuscripts from all countries in the English or Russian language.
