融液の挙動と結晶成長(<特集>バルク成長)

Crystal growers have often encounterd mysterious behaviors of melt during their operations of growing crystals from melts. The mysteries include l) relaxation of melt properties, 2) aging effect of melts, 3) critical superheating temperature and critical holding time, 4) stored crystal structure in melt, and 5) priming melt with solid chips. Some of the observed facts are described as examples of these mysteries. As a rational basis for intepreting these mysteries, the concept of the relaxation of a melt from the non-equilibrium state to equilibrium one was introduced. Then possible models for the melt structures to cause relatively long relaxation time was pointed out and the importance of study on the influence of the slow-relaxation melt to crystal growth was emphasized.
