HOCHZIRCONIUMOXIDHALTIGES GLAS UND DESSEN VERWENDUNGEN
摘要:
The invention relates to a glass containing a high proportion of zirconium-oxide, with the following composition (based on the weight percent of oxide): SiO2 54 - 72; Al2O3 0.5 - 7; ZrO2 ⊃10 - ∫18; B2O3 0 - ∫5; Na2O 2 - ∫10; K2O 0 - 5; with Na2O + K2O 2 - ∫10; CaO 3 - 11; MgO 0 - 10; SrO 0 - 8; BaO 0 - 12; with CaO + MgO + SrO + BaO ⊃5 - 24; La2O3 0 - 6; TiO2 0 - 4. The glass displays a high degree of chemical stability.
