• Cadmium sulfide vapor pressure measured by means of the glass membrane manometer method is discussed. The {log_<10>P, T^<-1>} curve consists of two straight lines corresponding to the temperature ranges below and above a critical temperature T_c (=740K). The sublimation enthalpy obtained from the straight line below T_c was 76.4k・cal/mol, which agrees well with the enthalpy of sublimation of the well-known reaction, CdS(s)=Cd(g)+(1/2)S_2(g). As for sublimation above T_c, it is concluded that, in addition to the said reaction, another reaction, CdS(s)=CdS_<1-x>(s)+(x/2)S_2(g), occurs which causes sublimation suppression, and that the activation energy necessary to create an excess of Cd (a sulfur vacancy) in a CdS crystal is 3.19 k・cal/mol or 0.138 eV.
