Lattice constants and thermal-expansion properties of the chromates and selenates of lead, strontium and barium

The lattice constants, space groups and linear coefficients of thermal expansion in the various axial directions were determined for the selenates and chromates of lead, strontium and barium. The lead and strontium compounds are monoclinic, while barium Chromate and selenate are orthorhombic (barite type).
