Abstract

Thermo-gravimetric analysis (TGA) and Fourier Transform Infrared Spectroscopy (FTIR) techniques for water content determination were compared with a neutron characterization technique, Prompt Gamma Activation Analysis (PGAA). Residual H content of the samples, heat treated at various temperatures, were measured with PGAA and compared with the results obtained from TGA data. Two major difficulties in TGA were overlapping of weight loss regimes due to removal of different species, and residual water that could not be removed, even though the samples were heated above 900 °C. After 3 h of heat treatment at 900 °C, 0.007 wt% H remained in the sample. FTIR spectra confirmed the presence of H semi-quantitatively. It is concluded that residual H remains even after high temperature treatments.
