Abstract:

Calculations and comparisons of average values of the standard Gibbs free energy for the formation of beryllium silicates are used to expand a known series that orders them by decreasing activity. The series is expanded to also include huegiant, barillite, spherobertrandite, eudidymite, beryllite, and chkalovite: chkalovite > beryllite > eudidymite > danalite > spherobertrandite > genthelvine > helvine > bertrandite > euclase > barillite > phenacite > beryl > huegiant. It is recommended that phenacite and the members to the left of it in the thermodynamically expanded series of silicate be used for direct sulfation, by-passing the expensive decomposition stage. Results obtained from calculation and comparison of average values of the standard Gibbs free energy of lithium silicates are used to construct another thermodynamically substantiated series that orders these minerals in decreasing order of reactivity: kuckite > bickitait > polylitionite > eucryptite > tainiolite = spudomen.
