| titleOfInvention | Transparent, essentially colorless, tin-fined las glass-ceramics with improved microstructure and thermal expansion properties |
| abstract | The object of the present application is β-quartz glass-ceramics (having very interesting optical, thermal expansion and feasibility properties), the articles including said glass-ceramics; the precursor glasses of said glass-ceramics, as well as the methods for elaborating said glass-ceramics and said articles. Said glass-ceramics having a composition, free, except for inevitable trace amounts, of arsenic oxide, antimony oxide and rare earth oxide, which contains, expressed in percentages by weight of oxides: 64 to 70% of SiO 2 , 18 to 24% of Al 2 O 3 , 4 to 5% of Li 2 O, 0 to 0.6% of SnO 2 , >1.9 to 4% of TiO 2 , 1 to 2.5% of ZrO 2 , 0 to 1.5% of MgO, 0 to 3% of ZnO, >0.3 to 1 of CaO, 0 to 3% of BaO, 0 to 3% of SrO, with BaO+SrO≤3%, 0 to 1.5% of Na 2 O, 0 to 2% of K 2 O, with 0.2<(MgO+Na 2 O+K 2 O)/Li 2 O≤1, 0 to 3% of P 2 O 5 , less than 250 ppm of Fe 2 O 3 ; and their crystallites, present in said β-quartz solid solution, have an average size of less than 40 nm, advantageously less than 35 nm, very advantageously less than 30 nm. |
