Li 2O–Al 2O 3–SiO 2 glass with CaO, MgO and TiO 2 additive were investigated. With more CaO + MgO addition, the crystallization temperature ( T p) and the value of Avrami constant ( n) decreased, the activation energy ( E) increased. The mechanism of crystallization of the glass ceramics changed from bulk crystallization to surface crystallization. With more TiO 2 addition, the crystallization temperature decreased, E and n had a little change. The crystallization of the glass ceramics changed from surface crystallization to two-dimensional crystallization. Plate-like, high mechanical properties spodumene-diopside glass ceramics were obtained. The mechanical properties related with crystallization and morphology of glass ceramics.
