PROCESS FOR MANUFACTURE OF PURIFIED ALKALINE EARTH METAL CARBONATE

摘要

Process for the production of purified alkaline earth metal carbonates. The present invention relates to a process for the production of refined alkaline earth metal carbonates, refined alkaline earth metal carbonates obtainable by the process, and their use in the manufacture of electronic technology and glassware products and devices. The process includes the step of calcining an alkaline earth metal carbonate in an aqueous phase comprising the salt. The alkaline earth metal carbonate may be barium carbonate or strontium carbonate.
