Abstract

Mixtures of A1(OH)3 gel and Mg(OH)2 were stored for 14 months in the solid phase in chambers with relative air humidity of 35%, 55%, 76% and 92%. IR spectra of the stored mixtures were measured. In mixtures stored at relative air humidity of 35% there were found no changes in IR spectra, while the mixtures stored at relative air humidity of 92% proved to exhibit IR spectra characteristic for hydrotalcite.
