Standard Enthalpy of Cu2SnS3 (Mohite) Formation from Sulfides

Copper tin sulfide Cu 2 SnS 3 (mohite) is the endmember of the binary system Cu 2 SnS 3 –Me II S, in which a number of four-component compounds (known as stannic minerals) are formed; it is also a representative of a large number of solid solutions, some occurring in nature and used in metallurgy and as promising materials for the production of solar cells. The standard enthalpy of mohite formation from covelline (CuS) and herzenbergite (SnS) has been determined: 2CuS + SnS → Cu 2 SnS 3 , (Cu 2 SnS 3 ) = ‒(51.01 ± 1.26) kJ/mol. The standard enthalpy of Cu 2 SnS 3 formation from elements kJ/mol has been calculated using reference data: (Cu 2 SnS 3 ) = –(263.79 ± 2.28).
