Abstract The effect of replacement of Al2O3 by ZnO on the sintering and crystallization behavior of MgO–Al2O3–SiO2 system glass-ceramics was investigated. The results show that with increasing ZnO content the melting temperature and crystallization temperature of the glass-ceramics were lowered and the glass transition temperature firstly decreased and then increased.

Now let s look at a surface crack in a ceramic. Unlike in a metal the atoms of the ceramic cannot move easily past one another. So instead of the material blunting the surface crack as occurs in metals in a ceramic the stress from the crack ends up concentrated at the point of the crack. This can lead to the material fracturing as shown in
