ABSTRACT:
A process for producing granulated strontium carbonate in which strontium oxide, strontium hydroxide or hydrated strontium hydroxide, and optionally water, is added as the binder and is granulated and dried simultaneously or in any desired sequence. In a preferred embodiment, the material to be granulated or the granulated material does not come into contact with any inorganic refractory material during any of the process steps. The resulting strontium carbonate obtained according to the process is free of added foreign ions and, in accordance with a preferred embodiment, also free of inorganic refractory materials, and is suitable for use, for example, as the basic material in the manufacture of glass.
