Synthesis of rare-earth chromates in the presence of certain oxides

Synthesis of rare-earth chromates in the presence of certain oxides The effect of Al2O3, SiO2, MgO, 3Al2O3·2SiO2 on the synthesis of LnCrO3 (where Ln=Nd, Sm, Yb) at high temperatures is considered. Chromium oxide in all the compositions Ln2O3−Cr2O3−Al2O3 (SiO2, MgO, 3Al2O3·2SiO2) reacts mostly with Ln2O3, i.e., silicon oxide alumina, magnesium oxide, and mullite do not interfere with formation of rare-earth chromates. This makes it possible to predict high durability for LnCrO3 electric heaters operating in contact with corundum, dinas, aluminosilicate, and periclase refractories in laboratory and industrial furnaces. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Refractories and Industrial Ceramics Springer Journals
