Coordination of Aluminum Ions in Tricalcium Aluminate
The coordination of aluminum ions in tricalcium aluminate (3CaO·Al2O3) was examined using infrared absorption, X·ray emission spectroscopy, and molar refraction techniques. Each of these methods indicated the presence of aluminum in fourfold coordination. No evidence was found for aluminum in sixfold coordination. The isomorphous substitution of Sr2+ for Ca2+ and Ga3+ for Al3+ and a comparison between the absorption frequencies for an SiO4 group and an AlO4 group were used to identify the infrared absorption bands in tricalcium aluminate.
