Estimating the term…
The present invention discloses a glass material, and a preparation method and a product thereof. The glass material contains a lithium salt crystalline phase and a phosphate crystalline phase. For the entire material, the crystallinity is 40-95%, the lithium salt crystalline phase accounts for 40-90 wt % of the entire material, and the phosphate crystalline phase accounts for 2-15 wt % of the entire material, wherein the lithium salt crystalline phase is one or more of lithium silicate, lithium disilicate and petalite, and the phosphate crystalline phase is aluminum phosphate or/and aluminum metaphosphate. After the glass material of the present invention is toughened, the Vickers hardness (Hv) is 900 kgf/mm2 or above. The glass material or a substrate of the present invention is suitable for protective members such as mobile terminal equipment and optical equipment and has high hardness and strength. Furthermore, the present invention may also be used for other decorations such as outer frame members of portable electronic equipment.
