Аннотация: Metastable phase relations in the PbO-GeO2 system have been studied by DTA and X-ray powder diffraction. Metastable equilibrium was acquired during the solidification of a melt while it was slowly (at 8 K/min) cooled from temperatures slightly exceeding the critical value for a given composition. In the metastable equilibrium acquiПоказать полностьюred in this way, alpha-PbO-base solid solution and four metastable individual phases were observed in the system at room temperature, with different structures and different thermal stabilities. A metastable equilibrium phase diagram has been mapped.
