Abstract

Abstract New inorganic pigments based on rare earth molybdenum mixed oxides: RE2Mo2O9 (RE = La or Pr) have been synthesized with a goal of preparing environmentally secure colorants. Characterizations using XRD, UV–vis spectroscopy, and CIE 1976 color coordinates assessment reveals the formation of compounds displaying colors: white for La2Mo2O9 and yellow-green for Pr2Mo2O9. The prepared pigments consisting of nontoxic elements and further found to be thermally and chemically stable.
