Some Novel Phases in Binary System of PbO-Sb2O3

摘要

In this study, we have investigated the PbO-Sb2O3 binary system. PbO and Sb2O3 are reacted using different stoichiometric ratios at 650 °C in an air using a gold and a platinum reaction vessel by heating for 24 h. PbSb2O6, Pb9Sb8O_(21), Pb4Sb2O8, Pb9Sb8O_(17), Pb6Sb2O_(11), Pb5Sb2O9, Pb7Sb2O_(11) Pb8Sb2O_(12), Pb9Sb2O_(13), phases are synthesized and these phases 0.5, 0.692, 0.8, 0.818, 0.857, 0.87, 0.875, 0.88, 0.9 mole fractions, respectively. Reaction products are characterized by the X-ray powder diffraction and by DTA/TG analysis methods.
