ABSTRACT:
A method of precipitating calcium borates from an aqueous mixture of calcium chloride and borax is disclosed. The yield of calcium borate precipitates can be increased by increasing the concentration of borax. Preferably, an increase in the calcium concentration also is employed. In general, it was found that properties of compacted glass batch produced from these calcium borates compare favorably with those compacted from standard glass batches.
