Title: Raman spectroscopy and principal factor multivariate curve resolution analysis of concentrated A1[sub 2]O[sub 3]-Na[sub 2]O-H[sub 2]O solutions

OSTI ID:976382

Principal factor multivariate curve resolution has been applied to a series of Raman spectra for samples representing, highly concentrated alkaline aluminate slurries. Factors are extracted that represent the behavior of the dominant chemical species present, including aluminate monomer, aluminate oligomers, water, and hydroxide. The analysis is particularly useful in unraveling the numerous contributions in the v(0H) region of the spectrum. These extracted factors were further examined by comparing their scores to measured physiochemical properties such as density, relative humidity, and molar concentrations of components, weight fractions, and water activity.
