摘要： 本揭示內容之實施例係關於一種強化玻璃製品，其包括**表面及與該**表面相對的第二表面，該等表面界定約小於約1.1 mm之厚度(t);壓縮應力層，其自該**表面延伸至約0.1·t或更大之壓縮深度(DOC)，以使得當該玻璃製品斷裂時，該玻璃製品碎裂成具有約5或更小之縱橫比的複數個碎片。在一些實施例中，在利用90粒SiC粒子在25 psi之壓力下研磨5秒之後，該玻璃製品展現約20 kgf或更大之等雙軸撓曲強度。本案亦揭示併入有本文所述的該玻璃製品之裝置及用於製得該玻璃製品之方法。 Embodiments of this disclosure pertain to a strengthened glass article including a first surface and a second surface opposing the first surface defining a thickness (t) of about less than about 1.1 mm, a compressive stress layer extending from the first surface to a depth of compression (DOC) of about 0.1•tor greater, such that when the glass article fracture, it breaks into a plurality of fragments having an aspect ratio of about 5 or less. In some embodiments, the glass article exhibits an equibiaxial flexural strength of about 20 kgf or greater, after being abraded with 90-grit SiC particles at a pressure of 25 psi for 5 seconds. Devices incorporating the glass articles described herein and methods for making the same are also disclosed. | Embodiments of this disclosure pertain to a strengthened glass article including a first surface and a second surface opposing the first surface defining a thickness (t) of about less than about 1.1 mm, a compressive stress layer extending from the first surface to a depth of compression (DOC) of about 0.1•t or greater, such that when the glass article fracture, it breaks into a plurality of fragments having an aspect ratio of about 5 or less.
