Preparation of granulated alkaline earth metal carbonate |
摘要 |
A method for preparing granulated alkaline earth metal carbonate, particularly barium carbonate or strontium carbonate, by adding a binding agent and optionally water; granulating the resulting mixture, preferably in the presence of water; drying the granular product; and optionally subjecting the granular product to a high-temperature treatment, in which the material to be granulated and the granulated material do not contact any inorganic refractory material during the granulation, during subsequent drying, and during any high-temperature treatment.
