摘要
Studies utilizing differential thermal analysis (DTA) to investigate the growth of single crystals are reviewed. Most such studies have dealt with equilibrium phenomena: melting and solid-solid transformations of compounds to be grown as single crystals; and phase diagrams (liquid-solid equilibria) of systems to determine congruently melting compositions and concentration and temperature intervals for the growth of bulk crystals or epitaxial layers from high-temperature solutions. Non-equilibrium phenomena that interfere with the equilibrium ones listed above can also be investigated by means of DTA: the formation and transitions of metastable phases; and the undercooling and delay of the nucleation and/or growth of crystals. Further possibile applications of DTA measurements in relation to the growth and investigation of single crystals are outlined and the usefulness of the DTA method is evaluated.
