从理论角度来看，胶体混合物的“硬球状”颗粒概念的有效性受到质疑。这涉及一类伪二元混合物，其中胶体之间的非空间相互作用是“残余的”（范围非常小，强度中等）。结果表明，与普遍预期相反，这种相互作用可能会对理论相图产生意想不到的影响。强调了这种情况与真正的溶质-溶剂混合物之间的区别。
The validity of the concept of "hard-sphere-like" particles for mixtures of colloids is questioned from a theoretical point of view. This concerns the class of pseudobinary mixtures in which the nonsteric interactions between the colloids are "residual" (with very small range and moderate strength). It is shown that contrary to common expectation, such interactions may have unexpected consequences on the theoretical phase diagram. The distinction between this situation and true solute-solvent mixtures is emphasized.
