Recent Progress in Hydrothermal Quartz Crystallization
Because of its unique piezoelectric properties α-quartz is a singularly important material in electronics and after Si comprises the largest volume Single crystal prepared commercially. The high-pressure crystallization of quartz under hydrothermal conditions has a long and distinguished history which will not be reviewed here. The reader should consult one of several recent reviews [1,2]. High-pressure conditions are required so that temperature and solvent density may be kept in a range where the solubility of α-quartz is sufficient to allow controlled crystal growth. The apparatus  and physical chemistry of quartz solubility , growth  and impurity partition  have been well studied and the reader should consult recent papers for this information. In this paper we review three new developments in quartz growth: (1) Alternative nutrient to that available from Brazil as feed stock for recrystallization; (2) the elimination of strain and cracking in quartz; and (3) the preparation of dislocation-free quartz.
