Abstract

La désagrégation alcaline de cassures de verre est réalisée sans traitement préalable de celles-ci On peut obtenir une solution de carbonate alcalin ou une solution de silicate alcalin, ainsi que des matières d'une grande surface spécifique, en broyant du verre à base de silicate et en le traitant ensuite, dans un autoclave, avec une solution contenant du carbonate alcalin, à une température de plus de 100 degrés C, de préférence supérieure à 130 degrés C. La désagrégation peut être accélérée par l'addition d'hydroxyde alcalin pour réaliser le procédé en cycle fermé. La solution contenant du carbonate alcalin est obtenue par carbonisation de la solution de silicate alcalin formée par désagrégation.
