摘要：
Based on experimental and prognosticated values of changes in the standard Gibbs energies of formation (Delta(f)G degrees) of a number of uranophosphate compounds and phosphates of various metals, expansions of potentials over oxide constituents have been obtained by using methods of linear programming. The resulting system of additive contributions was used to calculate Delta(f)G degrees for minerals that belong to the class of uranophosphates. The estimation errors are analyzed and the suggested algorithm is compared with correlation methods.
