The disclosure relates to a method of forming samples of alloys of group II-VI compositions having minimum dislocations, comprising the steps of providing a sample of a group II-VI compound, providing an enclosed ampoule having the sample at one end portion thereof and a group II element of the compound at an end portion remote from the one end portion, heating the sample to a temperature in the range of 350 to the melting temperature of the compound for about one hour while maintaining the group II element at a temperature more than 200 DEG C. below the sample temperature, heating the group II element to a temperature from about 5 DEG to about 50 DEG C. below the temperature of the sample while maintaining the sample at a temperature in the range of 350 DEG to 650 DEG C. both of about 15 minutes to about 4 hours, and then stoichiometrically annealing the sample at a temperature below 325 DEG C.
