A method has been developed for the utilization of salts of heavy metals generated due to chemical regeneration of complexes of concentrates after the baromembrane treatment of polluted waters. This method implies the immobilization in glass-ceramic matrices. The optimal composition of matrices was determined and their physico-mechanical properties were investigated. The matrices featuring good performance characteristics and good decorative effect were also obtained. On the basis of investigations performed a production process was developed and proposed for manufacturing the glass-ceramic materials used in construction and paint-and-varnish industries.
