摘    要:在自然界中硫化物晶体的种类较多,其结构较复杂,其中硫离子以S2-和对硫S2-2形式存在.一部分晶体的生长习性得不到满意的解释.本文采用配位多面体生长习性法则合理地解释了MoS2、ZnS、CuFeS2和PbS晶体的生长习性.发现MOS2晶体的生长习性为六方平板状{0001},其各晶面的生长速度为:V<0001><V<1010>;CuFeS2和ZnS晶体的生长习性为四面体,其各晶面的生长速度为:V<111>>V<001>>V<111>;PbS晶体的生长习性为八面体{111},立方体只是它的一种习性变化.

关 键 词:MoS2  ZnS  CuFeS2  PbS  生长习性

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 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: 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-
Keywords:MoS_2  ZnS  CuFeS_2  PbS  growth habit
