Abstract

L'invention concerne le domaine de la fabrication du verre et plus précisément du perfectionnement des technologies de fabrication de charge permettant la synthèse de verres au phosphate dans des techniques de production à fort tonnage. Le procédé consiste à préparer une charge de verre à la base de l'acide orthophosphorique, des oxydes et des sels de métaux, à cuire la charge et à produire une pâte de verre. La préparation de la charge de verre comprend trois stades: au premier stade, on prépare séparément la pulpe phosphatée à base d'acide orthophosphorique et d'oxydes des éléments des groupes 3 - 5 du tableau périodique et/ou un des sels de métaux alcalino-terreux puis on prépare séparément la suspension alcaline à base d'une solution de sels de métaux alcalins et de sels de métaux alcalino-terreux et/ou de métaux de transition d'alliage. Au deuxième stade, on effectue la neutralisation de la pulpe phosphatée par la suspension alcaline au moyen du mélangeage de ces solutions. Au troisième stade, on fait sécher la solution de pulpe neutralisée et l'on recuit la charge afin de finaliser les interactions chimiques; la cuisson de la charge sèche ainsi obtenue se fait jusqu'à ce qu'un bain de fusion uniforme soit atteint à 800 - 1250 °C.
