Lithium-aluminosilicate glasses with different zirconia (ZrO2) concentrations were prepared by a melting-quenching method. Glass slices were treated using a two-step chemical strengthening method below glass transition temperature (Tg). The effect of ZrO2 addition on the glass stability, hardness and chemical strengthening performance was investigated. The results show that the Tg increases with the increase of ZrO2 concentration in the range of 0-5% (in mole fraction). The absence of crystallization peaks indicates these glasses are rather stable. An appropriate addition of ZrO2 can promote the Li+-Na+ ions exchange and increase the layer depth. The surface compression stress (σc) increases with the increase of the ZrO2 concentration and reaches a maximum value of 1 055.6 MPa at 4% ZrO2 concentration. The center tension firstly increases and then decreases slightly with the increase of the ZrO2 concentration, indicating that these glass samples have a good shock resistance. The addition of ZrO2 has little effect on the hardness of glasses after chemical strengthening. Although the addition of ZrO2 decreases the crack resistance, these glasses still have a good crack resistance performance after chemical strengthening.
