On the Crystal Growth of Cadmium Sulphide

Abstract

The crystal growth of CdS has been investigated in detail mainly by the method of sublimation and recrystallization in the flow of nitrogen gas, with special reference to the process of growth and the forms of grown crystals, and the conditions have been searched for under which various kinds of crystal forms such as needle, lamina, plate, rod, block, twin and whisker forms are grown. To this end, the degree of vaporization in sublimating region, the temperature and saturated vapor pressure in growing region, the thermal decomposition, the origination of growth as well as the effect of dislocation upon crystal growth have been investigated. Further, the degree of perfection and luminescence of grown crystals have also been observed.
