Phase equilibria and thermal analysis of Si-C-N ceramics

A thermodynamic description of the In-Sn-Zn ternary system, which is of technical importance to optimize lead-free solder alloys, is presented using the CALPHAD method. Phase equilibria, such as isothermal and vertical sections, liquidus projection and mole fractions of the phase constitution, and thermochemical quantities were calculated and compared with the experimental data. They are in excellent agreement in most cases.
