摘要：

This paper presents a physicochemical study of poorly explored compounds in the zirconia-germania system. Reactions between these oxides were investigated by differential scanning calorimetry and thermogravimetry. The morphology of the reaction products was studied by scanning electron microscopy. The reaction products of ZrO2 and GeO2 powders were characterized by quantitative phase analysis. X-ray diffraction and Raman spectroscopy data indicate the formation of the germanates Zr3GeO8 and ZrGeO4. These compounds are shown to be substitutional solid solutions, and their homogeneity ranges are determined. GeO2 dissolution in ZrO2 stabilizes its tetragonal structure.
