Studies on some Glasses and Glass-Ceramics for Various Applications Including Seals
Glass and glass-ceramics (GCs) find wide applications in various disciplines of science and technology including sealing, vacuum, energy devices because of their desired thermomechanical, electrical, optical properties and chemical durability. We shall report here some recent studies carried out on thermo-physical and structural properties of TiO2 doped sodium aluminophosphate (NATP) glasses, interface studies on Li2O-ZnO-SiO2-P2O5-B2O3-Na2O (LZS) glassceramics for matched type of seal with Cu metal and machinability of magnesium aluminium silicate (MAS) glass-ceramics suitable for high voltage and ultra high vacuum applications. Structural studies have been carried out using XRD, FTIR, Raman and scanning electron microscopy(SEM). Thermo-physical measurements carried out on NATP glasses have been discussed in the light of structural properties.
