Growth Habit of the Sulphide Crystal

There are many kinds of sulphide crystals in the nature. Their crystal structures are complicated in which S ions exist in the form of S2- 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 MoSz is hexagonal platy {0001}. The relationship between different crystal fares in growth rate is: V0001 V1010; the growth habit of the CuFeS2 and ZnS crystals is a tetrahedra. The relationship between different crystal faces in growth rate is: V111 V001 V111 ; the growth habit of PbS crystal is an octahedron {111}, its habit change is a cube-
