ABSTRACT: The effects of Co2O3 on the crystallization and colorization of lithium aluminosilicate glass
ceramic were investigated by
using differential thermal analysis (DTA), X-ray diffractometry (XRD) and
scanning electron microscope (SEM). The results showed that the introduction of Co2O3 not only changed the color of lithium aluminosilicate glass but also affected its crystallization by increasing the
crystallizing maximum peak temperature (Tp)
and weakening the crystallization ability. In addition, the color of LAS glass ceramics could be achieved by controlling the
suitable Co2O3 and appropriate crystallization temperature.
