Effect of α-Al₂O₃ Particle Size in a Slurry on the Physical Properties of Chemically Strengthened Thin Glass Prepared by the Spray Method.

ABSTRACT: Chemical strengthening is considered as the most suitable method for strengthening thin glass sheets used in mobile phones. The spray method of chemical strengthening requires a slurry to be sprayed on the glass sample to be strengthened. This slurry is prepared by mixing various compounds. In this study, the influence of α-Al₂O₃ particle size in the slurry on the physical properties of the chemically strengthened glass prepared by the spray method was investigated. The compressive stress (CS) was dramatically enhanced as the particle size of Al₂O₃ in the slurry decreased. The glass sample with 13 nm α-Al₂O₃ including the KNO₃-Al₂O₃ slurry exhibited the highest CS of 905 MPa, and the depth-of
