“…Examples include dislocations in NdAl 3 (BO 3 ) 4 grown from a BaB 4 O 7 flux, which also exhibit the refraction of dislocations on crossing growth sector boundaries . Most growth dislocations observed in flux-grown RbTiOAsO 4 ran parallel to the growth surface normal and were of pure edge character . These crystals also contained dislocations generated by inclusions which formed at growth sector boundaries during growth.…”

A short review of X-ray topographic studies of crystals grown from solution is presented. The dislocation configurations characteristic of such crystals are described, and Klapper's explanation in terms of minimization of the elastic energy of a dislocation per unit growth length is highlighted. It is shown that the principles apply to crystals grown not only from low temperature solution but also by hydrothermal growth and growth from fluxed melts. Recent studies of growth of protein crystals have found that they have similar dislocation configurations and characteristics to those of ionic and small organic molecule crystals grown from solution.

Solubility curves of KDP (KH 2 PO 4 ) in solutions with different pH values were measured. It was found that the solubility of KDP crystal increased with the reduction pH value of solution. Transparent KDP crystal was grown from solution with 1.5 pH by point seed. Chemical etching experiments revealed that pyramid sector of the crystal displayed more growth defects. Growth defects, such as growth striation and inclusion, were analyzed by white-beam synchrotron radiation X-ray topography. The reasons for the formation of these growth defects were discussed. Transmittance spectra test of both prismatic sector and pyramidal sector was performed.
