| Abstract: | Thermodynamic calculations and experimental studies have demonstrated that dissociation of natural phosphates in a low-temperature plasma involves partial calcium oxide evaporation. As a result, upon cooling gaseous products of the dissociated phosphate raw material, compounds containing condensed calcium phosphate are formed. The composition and properties of condensed calcium phosphates, which can be used as fertilizers, are discussed. |
