Abstract
The infra-red absorption of 2 : 1 and 3 : 2 mullites, and a series of heat-treated mullite starting materials of nominal composition 3Al2O3·2SiO2 prepared by the sol-gel process, are investigated in the spectral range 400-1400 cm-1 using the KBr powder method. It is shown that the intensity variation of the absorption band in the spectral range 1100-1200 cm-1 provides a useful empirical scale for the determination of mullite compositions. This absorption feature exhibits the superposition of three peaks, which are related to vibrations of the mullite specific tetrahedral units [SiO4], [AlO4] and [Al*O4] with frequency maxima at about 1165, 1130 and 1108 cm-1, respectively.
