异极矿的标准生成热力学函数
Standard thermodynamic functions for formation of hemimorphite
摘要
Abstract
It temperature of 363-563 K, the isobaric specific heat capacities Cp of dehydrated hemimorphite Zrj4Si2O7(OH)2 and hemimorphite Zn4SizO7(OH)2H2O were measured with Perkin Elmer Diamond DSC. Under constant pressure, the DSC curves of the heating and dehydrating process in 573.15-998.15 K were obtained. Converting the specific heat capacities Cp to the molar heat capacities Cp.m , the molar heat capacities as a function of temperature were fitted with least square methods. Based on concerned thermodynamic data, a thermodynamic cycle was designed, and the standard molar thermodynamic functions of formation ΔpHmΘ, ΔfSmΘ and Gibbs free energy ΔfGmΘ of Zn4Si2O7(OH)2 and Zn4MSi2O7(OH)2H2O under standard pressure and at temperature of 298.15 K were calculated.关键词
