Abstract

Abstract The article considers the processes of processing solid waste from the production of phosphoric acid - phosphogypsum - into composite inorganic materials. It is shown that heat treatment at a temperature of 1073 K leads to the formation of inactive calcium sulfate. Carrying out the heat treatment process under similar conditions in the presence of an organic reducing agent is accompanied by the formation of a composite material with a luminescent ability. A simple method for the disposal of large-tonnage production waste with the production of a demanded product is proposed.
