Structural characterization of electrodeposited boron

was derived from its vapour pressure in the temperature range of 1,400–1,480xa0K. The vapour pressure of TeO2 (g) was measured by employing a thermogravimetry-based transpiration method. The temperature dependence of the vapour pressure of TeO2 over the mixture Pr2TeO6 (s)xa0+xa0Pr2O3 (s) generated by the incongruent vapourization reaction, Pr2TeO6 (s)xa0=xa0Pr2O3 (s)xa0+xa0TeO2 (g)xa0+xa0½ O2 (g) could be represented as:
