    摘要: The present invention relates to glass, glass-ceramic materials, lamp reflectors and processes for making them. The glass material has a composition, by weight of the total composition, comprising 56–67% SiO2; 9–22% Al2O3; 3.4–3.8% Li2O; 1.8–2.6% ZnO; 1.5–2.5% MgO; 3.3–5% TiO2; 0–2.5% ZrO2; 1.5–3% B2O3; 0–6% P2O5; 0–0.6% F; less than 500 ppm Fe; and components resulting from effective amount of at least one refining agent. The glass-ceramic material of the present invention contains β-spodumene solid solution as the predominant crystalline phase, and can be obtained by proper thermal treatment of the glass-ceramic material.

    摘要: The present invention relates to glass, glass-ceramic materials, lamp reflectors and processes for making them. The glass material has a composition, by weight of the total composition, comprising 56–67% SiO2; 9–22% Al2O3; 3.4–3.8% Li2O; 1.8–2.6% ZnO; 1.5–2.5% MgO; 3.3–5% TiO2; 0–2.5% ZrO2; 1.5–3% B2O3; 0–6% P2O5; 0–0.6% F; less than 500 ppm Fe; and components resulting from effective amount of at least one refining agent. The glass-ceramic material of the present invention contains β-quartz solid solution as the predominant crystalline phase, and can be obtained by proper thermal treatment of the glass-ceramic material. The glass-ceramic material is particularly suitable for heat-resistant lamp reflectors which require a high surface smoothness Ra of lower than 75 nm, a low CTE between 25 and 300° C. of less than 10×10−7 K−1, and IR transmission at about 1050 nm of over 80% at a thickness of 3 mm.
