Phase diagram of a growing succinonitrile crystal in supercooling-anisotropy phase space

Abstract

The phase diagram of growing crystal patterns for succinonitrile is obtained experimentally in a supercooling-anisotropy phase space. The anisotropy of the crystal growth is changed by roughening the upper surface of the bottom plate of the thin crystal-growth cell. Various growing modes are observed, and the relation between regular dendritic and random diffusion-limited-aggregation-like crystals is discussed.
