Calcium phosphates and oxalates are the most frequently observed bio-mineral phases. Many kinetics studies have been carried out on their crystal formation and dissolution in supersaturated and under saturated solutions, respectively. Major parameters include supernatant solution concentration, ionic strength, pH, temperature and solid surface behaviors. The growth of the calcium phosphate phases such as di-calcium phosphate di-hydrate (DCPD), octa-calcium phosphate (OCP), hydroxyapatite (HAP), and fluorapatite (FAP) crystals are observed. The ability of a surface to nucleate mineral phases is closely related to the magnitude of the interfacial energies. CaSeHPO4 crystals are grown in laboratory growth environments by the author in agar gel medium. Many characterization studies are done using grown crystals, such as FTIR, TGA/DTA, etching, SEM and XRD of the grown crystals are carried out and the results are reported.
