    Abstract: A method for producing homogeneous ingots of an alloy in which one of the components thereof has a high vapor pressure includes the step of sealing the desired alloy components in a quartz ampoule sufficiently large to include a vapor space therein and heating the ampoule and its contents to at least a temperature at which the components will form a homogeneous liquid mixture. An example of an alloy which can be produced by the instant process is an alloy of cadmium, mercury and tellurium. The method of this invention also includes the steps of quenching the homogeneous alloy from the liquid to the solid state while maintaining a relatively high vapor pressure in the vapor space in the ampoule above the space occupied by the alloy. The high vapor pressure can be maintained in the vapor space by thermally insulating the vapor space during the quenching step. The preferable form of quenching is by immersing only a portion of the space occupied by the alloy in a quenching bath, for example, a quenching oil.
