Abstract:

Growth of ammonium chloride dendrites from aqueous solution is experimentally investigated. The growth rate upsilon and the radius rho of curvature of branches are measured as a function of the relative supersaturation Delta for steady and unsteady growth conditions. It is shown that the experimental results are quantitatively described by the dependences rho=a/Delta+b, upsilon=c Delta(2), where the factors for primary branches are a=(1.3 +/- 0.2).10(-7) m, b=(2.5 +/- 0.4).10(-7) m, and c=(2.2 +/- 0.3).10(-4) m/s. The factor c is found to be approximately 7 times smaller for the side branches than that for the primary branches. (C) 2015 Elsevier B.V. All rights reserved.
