Standard enthalpy of formation kesterite Cu2ZnSnS4

open access: yesГеохимия, 2019
The standard enthalpy of kesterite formation (Cu2ZnSnS4) is calculated from the calorimetric determinations of the enthalpy of its formation from simple sulphides: 2CuS + ZnS + SnS → Cu2ZnSnS4 using literature data on the standard enthalpies of the formation of simple sulphides.
