Abstrakt:	We have synthesized CaMoO4- and SrMoO4-based scheelite-like compounds and located the stability ranges of (Ca/Sr)1 – 3xBi2xMoO4 solid solutions (x = 0.2125). The materials with x ≥ 0.175 have been shown to undergo superstructure ordering related to the arrangement of cation vacancies in their structure. The reflection spectra of the solid solutions have been measured and their band gap for direct transitions has been shown to range from 2.8 to 3.5 eV. We have studied photocatalytic properties of the solid solutions using powder samples. The photocatalytic characteristics of Ca1 – 3xBi2xMoO4 under UV illumination have been shown to be comparable to those of titania. The electrical conductivity of Ca1 – 3xBi2xMoO4 is lower than that of Sr1 – 3xBi2xMoO4. [ABSTRACT FROM AUTHOR]
