Workshop on Effective Many-Body Interactions and Correlations in Soft Matter (2003. Lyon, France). We are grateful to M Dijkstra and R van Roij for sending to us their simulation results. We wish to thank M Baus and E Lomba for many useful discussions. We acknowledge financial support from the Dirección General de Enseñanza Superior e Investigación Científica (DGESCYT) under grants No BFM2001-1017-C03-03 (GR and CFT) and No BQU2001-3615-C02-01 (JAA) and from the Instituto de Salud Carlos III grant No 01/1664 (JAA).The low-density phase diagrams of charge-stabilized colloidal suspensions of the Derjaguin-Landau-Verwey-Overbeek theory with an approximate effective one-component Hamiltonian given by the volume term and effective pair interactions, and of the classical theory (without including the volume term), are obtained from the hypernetted-chain integral equation at low colloidal charges. In the salt-free case both phase diagrams exhibit a vapour-liquid transition with short-ranged colloid-colloid correlations. This phase separation is compared to the vapour-liquid transition found in binary mixtures of highly asymmetrical hard spheres.engjournal articlehttp://dx.doi.org/10.1088/0953-8984/15/48/013http://iopscience.iop.org/restricted access536Phase-diagramCompressibilityCrystallitesFluidsPointTermodinámica2213 Termodinámica
