Interferometric Study of MgSO₄^.7H₂O Single Crystal Growth Kinetics from Solution

The study of surface reaction controlled growth kinetics of a magnesium sulphate heptahydrate single crystal in [110] direction at T = 15 - 32.5 °C and σ = 0.0002 - 0.135 has been performed with the use of interferometric technique. At lower supersaturations the model of dislocation growth fits the experimental data; at higher supersaturations growth is accelerated due to polynuclear two-dimensional nucleation according to the "Birth + Spread" model.

Keywords: interferometry, growth rate, two-dimensional nucleation
