Abstract: A window includes a base region and a compressive stress region disposed on the base region. The compressive stress region includes Li+, Na+, and K+ ions. The compressive stress region includes a first compressive stress portion in which a concentration of the K+ ions decreases, a concentration of Na+ ions increases, and a concentration of the Li+ ions increases, from a surface of the window toward the base region. A second compressive stress portion is adjacent to the first compressive stress portion. In the second compressive stress portion, the concentration of the Na+ ion decreases and the concentration of the Li+ ion increases, from the first compressive stress portion toward the base region. The window thereby has a high surface compressive stress value and impact resistance.

Abstract: A glass strength evaluation apparatus includes a support unit, a plate disposed on the support unit and including a surface on which a glass article, which is a target to be tested, is disposed, a fixing jig disposed on the plate and a power unit lifting up or down the fixing jig in a vertical direction toward the surface of the plate. The fixing jig includes a body portion, which extends in the vertical direction and lower fixing bolts. A press-fitting member insertion opening is recessed from a bottom of the body portion to extend in an upward direction, lower fixing bolt insertion holes penetrate the body portion, from one side of the body portion, in a first horizontal direction intersecting the vertical direction, to be extended to the press-fitting insertion opening, and lower fixing bolts are coupled into the lower fixing bolt insertion holes.
