The enthalpies increments of the chemical elements for minerals of cancrinite groupAuthor(s): Oleg Viacheslavovich Eremin
The chemical elements increments for experimental values of standard enthalpies ïÂÂfHº for three cancrinite group minerals have been calculated bymeans of linear programming problems. The obtained increments have been used in calculations of ïÂÂfHº values for nine minerals of cancrinite group with known thermodynamic properties. The mean error of calculations makes about 1 %. The estimations for some minerals with unknown enthalpies have been carried out.
