Models of crystal growth were defined by comparisons of macroscopic growth kinetics with theoretical predictions. The classic Burton-Cabrera-Frank (BCF) theory has often been observed, but such growth is sometimes inhibited, thought to be due to impurities. Tests on the growth of barite crystals were undertaken using in situ observations and computer simulations of growth units. Strongly anisotropic growth of two-dimensional nuclei was observed, and structure-induced self-inhibition of spiral growth was seen.
