Abstract
We have shown that the lattice-gas model with four repulsive pair interacti on constants (corresponding to the four nearest coordination shells) on a s imple cubic lattice is a sufficient model to describe the main types of cat ion ordering in relaxors. The phase diagram, obtained by the cluster variat ion method, shows the sequences of transitions between the phases 1:2 -->1: 1 --> disordered and 1:2 --> disordered.
