Abstract

L'invention concerne un procédé d'obtention d'une charge de verre contenant du bore destinée à la formation de fibres de verre. Selon ce procédé, le bore est fourni par un composé choisi parmi l'acide borique, l'acide borique anhydre et la colémanite; et il consiste à introduire les ingrédients de la charge contenant du bore dans une zone de formation de pastilles, à agglomérer les ingrédients avec suffisamment d'eau libre pour produire des pastilles et à sécher les pastilles par chauffage à une température suffisante et pendant une durée suffisante pour produire des pastilles dures et non susceptibles de former de la poussière. Obtention de pastilles dures et ne formant pas de poussière.
