The melting temperature is obtained for different values of the ratio between the charges and/or masses of the two types of particles.

The importance of the commensurate/incommensurate configurations and the different normal modes to the melting phenomenon is studied. When the ground state consists of a nonsymmetric arrangement of particles new thermally induced structural phase transitions are found.
