摘要： A chemically strengthened glass ceramic includes strengthening layers respectively formed on opposite sides, and each of the strengthening layers includes a potassium strengthening layer and a sodium strengthening layer sequentially located from a surface to an inside of the chemically strengthened glass ceramic. A depth of the potassium strengthening layer is 0.01 micrometers (μm) to 5 μm. A depth of the sodium strengthening layer is greater than or equal to 0.1t, where t is a thickness of the chemically strengthened glass ceramic. An average transmittance of a three-dimensional (3D) chemically strengthened glass ceramic in an optical wavelength range of 400 nanometers (nm) to 700 nm is greater than or equal to 85 percent %; a b value of a Lab color chromaticity indicator is greater than or equal to −2.0; and a haze is less than or equal to 0.25%.

摘要： In embodiments, a precursor glass composition comprises from about 55 wt. % to about 80 wt. % SiO2; from about 2 wt. % to about 20 wt. % Al2O3; from about 5 wt. % to about 20 wt. % Li2O; greater than 0 wt % to about 3 wt. % Na2O; a non-zero amount of P2O5 less than or equal to 4 wt. %; and from about 0.2 wt. % to about 15 wt. % ZrO2. In embodiments, ZrO2 (wt. %)+P2O5 (wt. %) is greater than 3. When the precursor glass composition is converted to a glass-ceramic article, the glass-ceramic article may include grains having a longest dimension of less than 100 nm.

摘要： ZrO2-toughened glass ceramics having high molar fractions of tetragonal ZrO2 and fracture toughness value of greater than 1.8 MPa·m1/2. The glass ceramic may also include also contain other secondary phases, including lithium silicates, that may be beneficial for toughening or for strengthening through an ion exchange process. Additional second phases may also decrease the coefficient of thermal expansion of the glass ceramic. A method of making such glass ceramics is also provided.

摘要： A cooking apparatus top plate includes a glass ceramic substrate having a chemically strengthened uneven structure with an average surface roughness Ra of 0.1 to 1.0 μm. A cooking vessel is placeable on the top plate to be heating by the cooking apparatus. A method for processing a glass ceramic substrate includes forming a top surface to have an uneven structure and chemically strengthening the top surface that has the uneven structure. An induction heating apparatus includes a cooking apparatus top plate and a plurality of induction heating coils for heating the cooking vessel placed on the top plate.
