Influence of high and low gravity on convection around growing crystalsCrystals growing from solution lead to changes in solution concentration which normally lead to convection in a gravitational field. This enhances local supersaturation and changes the growth rate and shape of the crystal. Experiments are described where velocity is enhanced by moving the crystal through the solution, and reduced to low values by performing the growth experiments in the low g environment of a KC-135 aircraft parabola. Differences of refractive index enable the convection to be viewed in an optical system. Results show the importance of even low convection on growth, and the ultimate composition and habit of the crystal.
