Crystal growth from solution

WebCrystal Growth from Solutions A. Authier, K. W. Benz, M. C. Robert & F. Wallrafen Chapter 347 Accesses 1 Citations Abstract Gravity-related phenomena in crystal growth from solutions are reviewed in the first section of the paper. The second and third sections deal with solution growth experiments performed in space at high and low temperatures. WebThe chemical physics of crystal growth is discussed, along with solid growth techniques such as annealing, sintering, and hot pressing; melt growth techniques such as normal freezing, cooled seed method, crystal pulling, and zone melting; solution growth methods; and vapor phase growth.
