Abstract
A glass article includes a central layer including a first crystalline phase having a first coefficient of thermal expansion and a surface layer surrounding an entirety of the central layer and including a second crystalline phase having a second coefficient of thermal expansion smaller than the first coefficient of thermal expansion. Accordingly, the strength of the glass article may be improved.
Claims20
A glass article comprising:
- a central layer including a first crystalline phase having a first coefficient of thermal expansion;
- and
- a surface layer surrounding an entirety of the central layer so that the surface layer is disposed on a first surface of the central layer and a second surface of the central layer perpendicular to the first surface of the central layer in a cross-section, the surface layer including:
- a second crystalline phase having a second coefficient of thermal expansion smaller than the first coefficient of thermal expansion.
