Abstract
Calorimetrically determined enthalpy of kesterite (Cu2ZnSnS4) formation from simple sulfides 2CuS + ZnS + SnS → Cu2ZnSnS4 was utilized to calculate the standard enthalpy of formation of Cu2ZnSnS4 (from elements at a pressure of 105 Pa): \({{\Delta }_{f}}H_{{298.5}}^{0}\)(Cu2ZnSnS4) = −(467.62 ± 2.28) kJ mol–1.
