Thermal oxidation of indium phosphide in the presence of cerium(III) chloride was studied by ultrasoft x-ray and IR absorption spectroscopic measurements. The resultant oxide films are found to contain In2O3, InPO4, and phosphorus. The accelerated formation of indium phosphate is due to reaction of the InP substrate with the CeO2 forming during the preparation of the additive. The films contain small amounts of cerium and exhibit low dielectric strength.

Study of the behavior of Ca//3P//2O//8 on heating in presence of various metal oxides is important both for further improvement of the electrothermal process for production of elemental phosphorus and also for development of new methods for conversion of native phosphates, based, in particular, on dissociation in the phosphate component. The process can be made easier by varying the composition of the original reaction mixture of Ca//3P//2O//8 and SiO//2 by introduction of additives raising the rate of thermal dissociation of tricalcium phosphate. The additive used in the present investigation was titanium dioxide. The authors show by thermodynamic calculations and experimental investigations that introduction of titanium dioxide into an original mixture containing Ca//3P//2O//8 and SiO//2 increases the rate of thermal dissociation of tricalcium phosphate and the degree of transfer of phosphorus oxides into the gas phase. Decomposition of Ca//3P//2O//8 in presence of SiO//2 and TiO//2 proceeds through the stage of CaTiSiO//5 formation.
