Glass material, for thermal insulation applications, is hardened chemically to give a structured depth of alkaline ion concentrations from the surface with a given surface stress and core viscosity point
The glass material which has been chemically hardened, for thermal insulation applications, has a concentration of alkaline ions from the surface to a depth of at least 100 mu m, a surface stress of at least 200 MPa and a core viscosity point of at least 550[deg]C. The alkaline ions are preferably N...

| description | The glass material which has been chemically hardened, for thermal insulation applications, has a concentration of alkaline ions from the surface to a depth of at least 100 mu m, a surface stress of at least 200 MPa and a core viscosity point of at least 550[deg]C. The alkaline ions are preferably Na +>, Li +> and K +>. The glass has a thickness of 2-7 mm.
L'invention concerne une vitre ayant subi une trempe chimique de sorte à présenter un gradient de concentration en ions alcalins à partir de sa surface sur une profondeur d'échange d'au moins 100 m, une contrainte de surface d'au moins 200 MPa, et un point de viscosité à coeur d'au moins 550°C. La vitre est utilisable notamment dans le domaine de la cuisson domestique, en tant que porte de four à pyrolyse, poêle, cuisinière, pare-feu, insert de cheminée et plus généralement pour séparer deux atmosphères gazeuses aux températures différentes. La vitre est particulièrement résistante aux chocs thermiques. |
