A glass composition of Li20-15, Al203-11, Si02-74 wt% doped with 16 parts of Tio2 per 100 parts was melted and heat treated at 550 and 850 deg C. Thermal elongation of glass ceramics showed some discontinuity close to 300 deg C, indicating two different types of phase assemblages contributing to elongation.
