Presence and size of a face in the habit are conditioned by the value of relative growth velocity RA/R,,i,A with respect to the critical growth velocity. It has been established that during the growth of crystals only certain values of relative growth velocities RA/RcrilA occur. Faces of KBC crystal

Abstract
Faces of threeβdimensional crystals have been divided into edge and corner ones to describe the phenomenon of their disappearance and appearance during the crystal growth. The expression for the critical growth velocity governing the presence of corner faces has been derived and verified and the validity of the previous relationship (SZURGOT, PRYWER) for the edge faces confirmed. Three nearest neighbours control the presence of corner faces and two neighbours decide on the edge faces.

## Abstract The old standing problem of face morphology is discussed. A special emphasis is put on the macroscopically flat faces, appearing on small molecule crystals mostly during calm growth, under low supersaturations. As distinct, protein crystals are growing with macroscopically flat faces ev
## Abstract The velocity and shape of growth layers on the {100} faces of ammonium dihydrogen phosphate (ADP) crystals growing in aqueous solution at __p__H = 5.0 are compared with those previously reported for growth at __p__H = 3.8. The results are interpreted in terms of the adsorption of hydrat
The experimental results of an investigation of the surface morphology of the as-grown (100) faces of KDP single crystals grown on seeds from aqueous solutions containing different concentrations of Fe 3+ and Cr 3+ impurities are described and discussed. It was found that the behaviour of steps in t
