摘要

method for the recovery of basic reagents for the synthesis of glass zblan from purified solutions.in which two aqueous solutions are mixed in purified under appropriate conditions of temperature and weight relations, balance competingin order to obtain precipitation a product consisting of a double salt with low solubility, which is then separated from the solvent, e.g. by filtration.and used for the production of glass.
