Beschreibung
Zusammenfassung:	A photocurable sol-gel composition for the production of transparent and crack-free glass bodies, wherein the composition comprises a silicon sol-gel precursor, a photopolymerisable monomer, a transition metal precursor, an organic solvent and water. Methods for making photocurable sol- gel compositions and for making transparent and crack-free glass objects from photocurable sol-gel compositions are also disclosed. L'invention concerne une composition sol-gel photodurcissable pour la production de corps en verre transparents et exempts de fissures, la composition comprenant un précurseur sol-gel de silicium, un monomère photopolymérisable, un précurseur de métal de transition, un solvant organique et de l'eau. Des procédés de fabrication de compositions sol-gel photodurcissables et de fabrication d'objets en verre transparents et exempts de fissures à partir de compositions sol-gel photodurcissables sont également divulgués.
