Crystal Growth of Some Renal Stones Constituents: I. In vitro Crystallization of Trace Element and Its Characterization Studies

The urinary calculi formation is still now unknown problems and seems to be very complex phenomenon. The in vitro studies are carried out by artificial renal stone formation in silica gel medium. In general, it appeared that trace element (TE) contents in mixed structure are always between values of respective pure phases. It is also found that some of the toxic elements such as barium are related to the structure but not necessarily to environment influences as in the case of lead. Barium hydrogen phosphate crystals are grown in gel method then identified the optimum growth parameters. TE mixed crystals are grown in different growth parameters. The grown crystals are analyzed by XRD, TGA/DTA, and SEM.The results are recorded and reported.
