Abstract:

A rapid procedure for the determination of free water in minerals is described which makes use of the reaction CaH2 2H2O yields CaOH2 2H2. The pressure change caused by H2 in the reaction is measured and the corresponding moisture content calculated. Parallel determinations using oven drying were made in order to show the differences between the two methods. The hydride procedure measures only free water whereas the conventional heating method includes both free water and water of activated adsorption andor water of hydration involving adsorption energies greater than 5-10 Kcals per mole.
