| abstract | 65-70% by weight of SiO 2 , 18-23% by weight of Al 2 O 3 , 3.6-5.5% by weight of Li 2 O, 0.1-1.2% by weight of Na 2 O, 0.1-1.2% by weight of K 2 O, MgO 0 -1 wt%, CaO 0-1 wt%, SrO 0-1 wt%, BaO 0-1 wt%, ZnO 0.1-1.2 wt%, ZrO 2 1-4 wt%, TiO 2 0.5-1.7 wt%, CeO 2 0.1-1% by weight, As 2 O 3 0-1% by weight, Sb 2 O 3 0-1% by weight. Substantially contains Na 2 O and K 2 O and contains three or more components of MgO, CaO, SrO, and BaO among alkaline earth metal oxides, so that glass has excellent solubility and formability, good transparency, and a coefficient of thermal expansion close to zero. The present invention relates to crystallized glass having heat resistance, which can be used as a kitchen utensil, a heater panel, a telescope reflector, and a precision component material. |
