摘要: The transition of the Friedel phase to chromate-AFm in chromate solution and thermal stability products was investigated using analysis combined with mass spectrometry, X-ray diffraction Fourier transform infrared spectrometer. results indicated that Cr O 4 2− easily substituted for Cl forming chromate-AFm. chemical formula characterised as 3CaO·Al2O3·CaCrO4·12H2O. Chromate-AFm gave two steps dehydration, dehydroxylation one step redox reaction Cr(VI) whole heating process from 40 1000°C. spectra showed different OH-metal binding ways Freidel
