Abstract

A variety of 2D dendritic morphologies, such as orthogonal lattices, oblique lattices, curved weaves, and randomly branching morphologies, of a simple cubic crystal, NaCl, were selectively produced in a thin gel matrix by the tuning of branching growth modes with the variation of NaCl and gelatin concentrations. We characterized the crystal fabric of these specific patterns consisting of NaCl blocks. It is notable that particular curved branches were induced by gradual changes in the growth direction in asymmetric concentration fields. Straight and bending growth in the particular dendrites can be switched by changing the growth velocity in the gel medium.
