Abstract

Calcium oxalate monohydrate (COM) crystals were obtained by different methods. The tendency of COM to form splices, twins, spherulites and dendrites was demonstrated. The mechanism and kinetics of growth of two out of three basic faces were investigated by in situ atomic force microscopy. The rate of COM dissolution was revealed to increase in the presence of aluminum and iron ions. Substitution of Aqua RX water for distilled water also increased the dissolution rate..
