Β-quartz glass ceramic with controlled transmittance curve and high content of iron oxide and tin oxide, articles of said glass ceramic, precursor glass

摘要

-quartz lithium aluminosilicate (LAS) glass-ceramics contain neither arsenic oxide nor antimony oxide, are fined with tin oxide and include vanadium oxide, chromium oxide and a high iron oxide content (1500 ppm), and have a controlled transmission curve. Articles such as cook-tops can be made from such glass-ceramics.
