Abstract

Studies on the crystallization behaviour of SiO2 52.0, Al2O3 22.0, RO (CaO + MgO) 10.5, R2O (Na2O + K2O) 13.5, TiO2 6.0 (wt%) glass were carried out. The glass possessed fair working characteristics and corrosion of the melting pot was insignificant. The glass did not show any tendency towards deformation during crystallization. On crystallization, glass-ceramics possessing high mechanical strength (50,000 psi) and fair resistance to attack of alkali were obtained. The DTA curve exhibited exothermic peaks at 720° and 835°C. The principal crystal phases appearing at 760°, 835° and 930°C were identified as nepheline and sphene, while cordierite was also detected.
