%X By means of heating, the pre-crack healing of mica glass ceramics was studied. The results show that there are three stages in the process of crack healing, including crack surface concave shape and crack tip blunting, crack disintegrating and sphericizing to void and void healing. On the condition that there is no material commutation with outside, healing of internal crack and hurt of material depends on the move of internal material and the change of structure. Crack-healing of the series' glass ceramics is primarily influenced by healing temperature.
