When a polyhedral crystal grows from solution in a stable way, the supersaturation is not uniform over its interface (Berg effect). The rate of stable growth of a cubic crystal is determined by numerical calculations, by taking account of three dimensional diffusion field surrounding it and growth kinetics on the interface. It depends on the supersaturation σ_∞ at infinity as well as the crystal size L. Then, the shape stability is discussed. It is shown that a catastrophe occurs first at the center of the face, and the curve of stability limit, σ_∞ versus L, is obtained.
