Nanoscale disequilibrium in waste form apatites

Nanoscale disequilibrium in waste form apatites

Conversion of hazardous metallic elements to stable synthetic minerals by geological reactions was examined focusing on polluted soil treatment using apatite. CaO, PbO, V2O5 and CaF2 were treated in atmosphere at 800.DEG.C. to synthesize (PbxCa10-x)(VO4)6F2(0<x<9). The product was sintered for...
