Abstract The attachment energy and specific surface energy of important faces of a ZrAl_3 crystal have been calculated by computer using the periodic bond chain method and the Lennard-Jones n-m potential parameters. The equilibrium form and growth form of the crystal have been deduced, and the theoretical growth form has been compared with the actual growth form observed in a melt growth experiment.
