The　film　and　bulk　material　of　zinc　sulphide　were　prepared　by　chemical　vapor　deposition.　The　nucleation　and　the　growth　of　zinc　sulphide　crystals　deposited　on　the　graphite　and　quartz　substrates　with　different　roughness　were　observed.　The　grains　of　zinc　sulphide　deposited　on　the　substrate　surface　are　very　fine,　with　equiaxial　shape,　and　then　grow　up　into　columnar　shape.　The　roughness　of　the　substrate　surface　influences　the　nucleation　density　of　zinc　sulphide　but　has　no　effect　on　the　growth　rate　of　zinc　sulphide　crystal　in　the　thickness　direction.　The　thickness　of　zinc　sulphide　nearly　increases　with　incresing　the　deposition　time.　The　growth　rate　of　zinc　sulphide　increases　with　increasing　the　flow　of　H2S　and　vapoured　Zn.　The　growth　rate　exhibits　maxium　value　at　a　given　deposition　temperature.
