Popis: | The kinetics of calcite (CaCO(3)) crystallization on calcite seed crystals in the presence of taurine was investigated by the constant composition method. The presence of taurine (4 x 10(- 5)- 4 x 10(-4)M) in the supersaturated solutions lead to calcite crystals with a characteristic discontinuous planes of growth and poor habit, as compared to the hombohedral morphology of the seed crystals. The acceleration effect of taurine on the crystal growth rate was 17-96%. The apparent order of the crystal growth was found to be 2.0+/- 0.2 typical for a surface diffusion-controlled spiral growth processes. |
