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.
