Title (EN) METHOD FOR THE MANUFACTURE OF A SILICA GLASS PRODUCT
(FR) PROCEDE DE PRODUCTION D'UN PRODUIT EN VERRE DE SILICE
Abstract: front page image
(EN)The present invention relates to an inexpensive and productive method for the manufacture of a silica glass product of a comparatively complex shape. The above-noted object is achieved by a method for the manufacture of a silica glass product, which comprises: a step in which a sintered silica powder is mixed with water to form a high concentration silica glass slurry of solid component density 70 to 85 mass% which is cast in a mould, then dried, and subjected to a purification process, before undergoing a glass formation process.
(FR)La présente invention concerne un procédé de production peu coûteux et productif d'un produit en verre de silice présentant une forme comparativement complexe. Ledit objet est produit au moyen d'un procédé de production d'un produit en verre de silice qui consiste à mélanger de la poudre de silice frittée avec de l'eau pour former une pâte de verre de silice hautement concentrée d'une densité en matière solide comprise entre 70 et 85 % en masse qui est coulée dans un moule puis séchée et enfin, soumise à un procédé de purification, avant de subir un traitement de vitrification.
