摘要： The present invention discloses an aluminosilicate glass and a glass ceramics for chemical tempering, specifically a novel aluminosilicate glass comprising Li 2 O and P 2 O 5 for chemical tempering. The glass of the present invention can have a high ion exchange rate by adding 0.01-8 wt% of P 2 O 5 . The glass of the present invention comprises 2-6 wt% of Li 2 O, which can reduce the glass molten temperature and glass transition temperature. The glass of the present invention has a low glass transition temperature (Tg) of 480-590°C, and a glass hardness of at least 600 Kg/mm. The glass of the present invention has a large depth of the surface compressive layer (DoL) and a high surface compressive stress (CS) after being chemical tempered. After tempering in pure KNO 3 , a surface compressive layer of potassium ion can be formed with a DoL of at least 20 μm and a CS of at least 600 MPa. And tempering in mixed salts of KNO 3 and NaNO 3 or a two-step tempering by using KNO 3 and NaNO 3 can form potassium and sodium ion compressive layers at the same time with a DoL of at least 50 μm and a CS of at least 600 MPa. In addition, the aluminosilicate glass of the present invention can be further subjected to thermal treatment to convert to glass ceramics.
