Abstract
(EN)
Glass having a relatively high coefficient of thermal expansion and excellent thermal shock resistance. Components of the glass as expressed in molar percentages comprise: SiO2: 55-80%; B2O3: 0-10%; Al2O3: 0-10%; ZnO: 2-20%; MgO: 0-15%; Li2O+Na2O+K2O: not more than 30%. By means of an appropriate ratio of the components, the obtained glass has a relatively high coefficient of thermal expansion while simultaneously having excellent thermal shock resistance. The present glass is suitable for chemical strengthening. A glass product obtained after chemical strengthening has relatively large surface stress and a relatively deep stress layer depth.
(FR)
L'invention concerne du verre présentant un coefficient de dilatation thermique relativement élevé et une excellente résistance aux chocs thermiques. Les composants du verre selon l'invention comprennent, en pourcentage molaire : SiO2 : 55-80 % ; B2O3 : 0-10 % ; Al2O3 : 0-10 % ; ZnO : 2-20 % ; MgO : 0-15 % ; Li2O+Na2O+K2O : pas plus de 30 %. Un rapport approprié des composants permet que le verre obtenu présente un coefficient de dilatation thermique relativement élevé tout en étant simultanément doté d'une excellente résistance aux chocs thermiques. Le verre selon l'invention convient à la trempe chimique. Un produit de verre selon l'invention, obtenu après trempe chimique, présente une tension de surface relativement importante et une profondeur de couche de tension relativement profonde.
