| Abstract: | NIR FT-Raman spectrometer is used to in--situ study the carbonization process ofsodium aluminate solutions. From the Raman spectra acquired in this process, oscillation andnon--reproducibility are found. The experiment gives the result that Al (OH)4] anions whichexist at the beginning of carbinization process will decrease gradually with the time going,but Al2 (OH )10]4-- anions increase gradually at the same time. It demonstrates thatAl2 (OH)10]4-- anions and other polycondensation anions may be produced in the carbonization process. |
