Abstract

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.
