Abstract
A method is disclosed for preparing a crystalline ingot of Hg.sub.1-x.sbsb.o Cd.sub.x.sbsb.o Te. Before moving a heated solvent zone for progressively dissolving ingot sources and giving rise to a single ingot, an adaptation zone is created from a monocrystalline germ by heating and cooling the solvent in contact with the germ, the ingot obtained is monocrystalline. The method of the invention in particular reduces the manufacturing costs of components such as infrared detectors and avalanche diodes.
