Abstract: There are many kinds of sulphide crystals in the nature. Their crystal structures are complicated in which
S ions exist in the form of S^2- and S₂^2-. Of them, the growth habit of some crystals is not explained successfully. In this paper, the growth habit of
MoS₂，ZnS，CuFeS₂ and PbS were reasonably explained in terms of the coordination polyhedron rule. The growth habit of MoS₂ is hexagonal platy {0001}. The
relationship between different crystal faces in growth rate is: V_<0001><V_<1010>; the growth habit of the CuFeS₂ and ZnS
crystals is a tetrahedra. The relationship between different crystal faces in growth rate is: V_<111>>V_<001>>V_<111>；the growth habit of
PbS crystal is an octahedron {111}, its habit change is a cube.

Key words: MoS₂, ZnS, CuFeS₂, PbS, growth habit
