ABSTRACT: Kidney stones consist of various chemical compounds. Mineral oxalate monohydrate and dihydrate
is the main inorganic constituent of kidney stones. However, the mechanisms for the
formation of crystal mineral oxalate are not clear. In this field of study, there are many theories
including nucleation, crystal growth and or aggregation of formation of crystals .The effect of
some urinary species such as ammonium oxalates, calcium, citrate, proteins and trace mineral
elements have been previously reported by the author. The kidney stone constituents are grown
in the kidney environments, the sodium meta silica gel medium (SMS) provides the necessary
growth simulation (in-vitro). In the artificial urinary stone growth process, growth parameters
within the different chemical environments are identified. The author has reported the growth of
urinary crystals such as CHP, SHP, BHP and AHP. In the present study, SrNH4MgHPO4(Strontium Ammonium Magnesium Hydrogen Phosphate) crystals have been grown in three different growth faces to attain the total nucleation reductions. As an extension of this research, many characterization studies have been carried out such as FTIR, XRD, TGA/DTA, SEM and etching and the results are reported.
