摘要
通过 X 射线衍射、拉曼光谱和扫描电子显微镜方法研究了 CaMoO4-CaWO4 二元体系中固溶体的形成。CaMoO4 和 CaWO4 成分的混合物在 600-1200 °C 温度范围内烧结（以 100 °C 为增量）。通过差示扫描量热法研究了 CaMoxW(1-x)O4 体系在 x = 0.3 ... 1.0 范围内的固相。绘制了高达 1550 °C 的 CaMoO4-CaWO4 相图。得到 CaMoxW(1-x)O4 固溶体的最低烧结温度为 800 ℃。对 CaMoxW(1-x)O4化合物的阴极荧光研究表明，钼酸盐类发光强度更高。
Ca(Mo,W)O4 Solid Solutions Formation in CaMoO4-CaWO4 System
The formation of solid solutions in the CaMoO4-CaWO4 binary system is investigated by X-ray diffraction, Raman spectroscopy, and scanning electron microscopy methods. The intermixtures of CaMoO4 and CaWO4 components are sintered in 600—1200 °C temperature range (in 100 °C increments). The solidus of the CaMoxW(1-x)O4 system is studied by the differential scanning calorimetry method in the x = 0.3 … 1.0 range. CaMoO4-CaWO4 phase diagram is constructed up to 1550 °C. The minimal sintering temperature in order to get CaMoxW(1-x)O4 solid solution is shown to be 800 °C. Cathodoluminescence study of CaMoxW(1-x)O4 compounds showed higher intensity of molybdate luminescence type.
期刊介绍：
The journal Crystal Research and Technology is a pure online Journal (since 2012).
Crystal Research and Technology is an international journal examining all aspects of research within experimental, industrial, and theoretical crystallography. The journal covers the relevant aspects of
-crystal growth techniques and phenomena (including bulk growth, thin films)
-modern crystalline materials (e.g. smart materials, nanocrystals, quasicrystals, liquid crystals)
-industrial crystallisation
-application of crystals in materials science, electronics, data storage, and optics
-experimental, simulation and theoretical studies of the structural properties of crystals
-crystallographic computing
