Low-temperature crystal growth in aqueous systems

The conditions for the crystal growth of various substances (salts, amino a cids, and others) in aqueous systems between the eutectic (less than or equ al to0 degreesC) and room temperatures were studied. The ingots prepared by freezing solutions of required compositions were used as source material f or crystal growth (recrystallization). The growth and properties of the cry stals were shown to be controlled by the supersaturation which is maintaine d at the desired level by means of fractional ingot melting.
