Abstract  

The rehydration characteristics of a commercially produced hydromagnesite and two basic magnesium carbonates synthetically produced from Mg(OH)2, are presented. The products were dehydrated and dehydroxylated at 325C before rehydration was attempted. DTA and FT-IR were used to follow the structural changes that occurred during the rehydration processes. The results obtained for the commercially and synthetically produced hydromagnesite products indicated that the original symmetry of the groups was reclaimed during rehydration. This was not observed for the synthetically produced unidentified basic magnesium carbonate product. This investigation provides insight into the rehydration characteristics of a select group of basic magnesium carbonates.

coupled with Fourier transformed infrared (FT/IR). It was reported the TG-FT/IR pyrolysis experiment at low heating rates of biomass samples (wheat straw, tobacco) and pyrolysis yield was evaluated [ 3 ]. It was investigated palm oil waste, are the major

FT-IR spectroscopy is a useful method for mineralogical analysis of pottery and this method has been used by us for investigation of pottery since 1991 [ 3 – 8 ]. The FT-IR spectroscopy was applied mainly for the identification of crystalline phases

depolymerized CWS fractions, marked as CWS 30 and CWS 60 , were recovered after treatment by freeze–drying. Their molecular sizes, determined by HPLC, were estimated to be ~499,000 (CWS 30 ) and 185,000 (CWS 60 ). FT-IR spectra of all carboxymethyl
