RuO2 single crystals were obtained by evaporation of PbO from Pb2Ru2O6.5 at high temperatures and were verified as good standards for WDS analysis. They were used for the investigation of phase equilibria and the extent of solid solubility in the RuO2–TiO2 system by WDS quantitative microanalysis. The solid solubility at 1350 °C was determined to be 16.5% TiO2 in RuO2 and 13.5% RuO2 in TiO2.
