Abstract
Des articles de verre aux halogénures, p. ex. des tiges, des tubes et des préformes pour faire des fibres de verre aux fluorures, sont préparés par fusion et/ou moulage sous faible pression, p. ex. 0,01 à 500 mbars, et durant le régime à faible pression, on maintient un débit de gaz compris entre 0,01 et 100 litres par minute (mesuré à température et pression normales). On a constaté que de soumettre les produits de fusion à une faible pression réduisait l'atténuation de la fibre qui résulte éventuellement de la fusion.
