Higher Order Conditional Probability and Concentration-Concentration Fluctuation in the Long Wavelength Limit of Molten Binary Alloys
A thermodynamic model based on cluster of four atoms is considered to obtain conditional probability enumerating the higher order atomic correlation in the nearest neighbor shell of liquid binary alloys. This has enlightened the discussion of how the higher order atomic correlation is related to pairwise distribution. The Cd-Ga liquid alloy is a candidate of homo-coordination. Bi-Cd liquid alloy indicates partly homo-coordination. The higher order conditional probability of Bi-Cd binary alloy is uniformly displayed. There is band-like formation of the higher order conditional probability of Cd-Ga liquid alloy. The values of concentrationconcentration fluctuation and higher order conditional probabilities computed for Bi-Cd and Cd-Ga, are presented.
