Abstract

GLASS ceramic in the system Li2O-B2O3-SiO2 was prepared by adding different amounts of ZrO2 up to maximum saturation. DTA, XRD and SEM were used to study the crystallization behavior of these glass samples. Tetragonal and monoclinic zirconia, are the only crystallized phases obtained after different heat treatment schedules. Fraction of transformed ZrO2 and total intensity of ZrO2 were calculated. Microhardness was measured for different samples, and it was found to be depending on the amount of ZrO2 added and the heat treatment parameters. Sample contains 20 g ZrO2 and treated at 650ºC for 10 hr showed higher microhardness value (14.99GPa).
