Abstract
The techniques of scanning transmission electron microscopy (STEM) and electron energy loss spectroscopy (EELS) were used to perform microstructural and semiquantitative microchemical analyses of multiphase microstructures developed in bulk glasses by liquid immiscibility processes. Bulk glass samples were prepared in the systems SiAlO, CdGeSiAs, PbAlTiSiO, and SiNaBON, using synthesis procedures appropriate to each system. Representative compositions which exhibited a multi-phase glass microstructure in the transmission electron microscope (TEM) were selected for the STEM and EELS microchemical analysis. Glasses in all the systems always showed a microstructure of glass droplets (varying in size from ≈5 to ≈40 nm) dispersed in a glass matrix. The microstructure of the PbAlTiSiO glass showed two droplet phases (≈5 nm and ≈25 nm in diameter) embedded in a glass matrix. The results of the microchemical analysis are correlated with available liquid miscibility gap information, particularly in the AlSiO system.
