Shape of ammonium chloride dendrite tips at small supersaturation [PDF]

J. Cryst. Growth, 274 (2005) 233-240, 2004
We report detailed shape measurements of the tips of three-dimensional ammonium chloride dendrites grown from supersaturated aqueous solution. For growth at small supersaturation, we compare two different models: parabolic with a fourth-order correction, and power law.
