Abstract

E' descritto un procedimento per la produzione di carbonato di metallo alcalino-terroso granulato, in particolare di carbonato di bario e carbonato di stronzio. Nel procedimento si aggiunge un legante ed eventualmente acqua e si granula per effetto di forze meccaniche o in forma di una granulazione per sovracostruzione, per esempio in un reattore a evaporazione rapida con contemporaneo essiccamento. Di preferenza si granula in presenza di acqua. Poi si può sottoporre ancora il granulato a un trattamento ad alta temperatura. Né nella granulazione né nel trattamento ad alta temperatura il materiale granulantesi o granulato viene e contatto con materiale inorganico refrattario.
