Mössbauer spectroscopic studies on an as-synthesized sample of ferrisilicate analog of zeolite BETA, which was substantially free from Al (SiO2/Al2O3 > 2000) have been carried out at rt, 4.2 K, and in the presence of an externally applied field (4.13 T) at 4.2 K. The broadness of the sole peak in the spectra recorded at rt. and at 4.2 K, isomer shift (IS) of 0.22 mm/s at rt. and 0.32 mm/s at 4.2 K, and the quite narrow and sharp hyperfine sextet in the spectrum of 4.2 K with externally applied field (4.13 T), clearly demonstrate that most of the Fe3+ ions, if not all, are well dispersed and present in the tetrahedral framework of zeolite BETA.
