Equilibrium and Growth Forms of Sucrose Crystals in the <hkl> zone. 1. Theoretical treatment of (101)-d form.

Observed (h0l) growth forms of the sucrose crystal are compared with calculated ones, on the basis of attachment energy plots. Agreement is found for all forms only if a modification of character of the ( 101)-d face is taken into considation. Calculation of equilibrium and growth forms have been carried out using two potential foe dispersion and bond energy respectively. The same method is applied for studying the spiral growth shape on the (101) face and its field of validity is discussed: a low driving force values, the attachment energy at the steps is the relevant energy, determining the shape of spirals on (101) face of sucrose
