对1230 ~ 1750℃温度范围内sno2 - zro2相图的研究表明，存在不混相隙，形成（Zr1−xSnx） o2和（Sn1−yZry） o2两种有限固溶体。每种固溶体合成了四种成分，得到了纯相，并通过室温和高温x射线衍射进行了表征。测定了四角形（Sn1−yZry）O2、单斜形（Zr1−xSnx）O2和四角形（Zr1−xSnx）O2的单元胞参数，并与取代原子的含量进行了相关性分析。当锡摩尔分数变化时，（Zr1−xSnx） o2系列的单斜向四方反应和反转反应也被表征（转变温度）。
The study of the SnO2–ZrO2phase diagram in the 1230–1750 °C temperature range has shown the existence of an immiscibility gap, leading to two (Zr1−xSnx)O2and (Sn1−yZry)O2limited solid solutions. Four compositions were synthesised for each solid solution, leading to pure phases, which were characterised by room-temperature and high-temperature X-ray diffraction. The unit-cell parameters of tetragonal (Sn1−yZry)O2, monoclinic (Zr1−xSnx)O2and tetragonal (Zr1−xSnx)O2were determined and correlated with the content of the substituted atom. The monoclinic to tetragonal and reverse reactions for the (Zr1−xSnx)O2series were also characterised (transition temperatures) when varying the tin mole fraction.
