Phase formation in the system of Pb-Mo-O and synthesis of lead molybdate PbMoO4 by sputtering ion beam

The laws governing the synthesis of PbMoO4 lead molybdate thin films obtained by the ion beam sputtering method are considered. The synthesis of thin PbMoO4 films using sputtering with two ion beams is considered. This technique allows independent sputtering of two targets of the reacting components (lead oxide PbO and molybdenum trioxide MoO3) with the formation of gaseous particle fluxes that arrive on the surface of the substrates, where the synthesis of lead molybdate occurs. Modeled phase equilibriums in the Pb-Mo-O2 system at a pressure of 10-3 Pa. The fields of crystallization of coexisting phases are revealed. The grown thin PbMoO4 films were oriented, polycrystalline, and had scheelite structure. A model of the formation of PbMoO4 layers on the surface of fused silica SiO2 is discussed. An analysis of growth processes. An X-ray phase analysis of the samples was carried out. The study showed that the formation of thin films of PbMoO4 is a complex physicochemical process.
