Abstract
A chemically toughened microcrystalline glass has a Na/Li exchange layer, and has a compressive stress layer. A depth of the compressive stress layer and a total thickness t of the chemically toughened microcrystalline glass meet the following: the depth of the compressive stress layer is 0.15 t to 0.22 t. In addition, a compressive stress intensity CS50 at a toughening depth of 50 μm in a surface layer of the chemically toughened microcrystalline glass and the total thickness t of the chemically toughened microcrystalline glass meet the following: CS50 is 130+(20 t−13)×15 Mpa to 230+(20 t−13)×15 MPa. In addition, CS50 and the depth of the compressive stress layer meet the following: CS50/(Doc−50) is 1.4 to 6.
