OSTWALD RIPENING GROWTH-RATE FOR NONIDEAL SYSTEMS WITH SIGNIFICANT MUTUAL SOLUBILITY .2. TERNARY-SYSTEMS - APPLICATION TO LIQUID-PHASE SINTERING OF W-NI-CR

Equilibrium equations are developed to describe local interface curvature effects for a two phase nonideal ternary system. Unlike the binary case, the additional degree of freedom does not permit a unique determination of Ostwald ripening conditions from equilibrium considerations. The LSW theory is extended to include nonideal solution behavior and solid solubility in a ternary system. Theoretical predictions are compared with experimental data and explain the growth rate dependence on composition.
