โœฆ Synopsis

Striations were observed on nickel heated in 'uacuo at 900ยฐC. The distribution of striating orientations suggests the presence of point cusps in the plot of surface free energy at (loo), ( 110) and (210) orientations and a line cusp between (410) and (510). Also evidence was found that surface diffusion is fast at (110) and for a range of atomically rough planes between (410) and (210) in addition to the smooth ( 100) and (111) planes. Both effects are ascribed to impurity adsorption.

## Abstract The effect of crystal surface roughness on impurity adsorption was investigated in a fluidized bed crystallizer and in a batch crystallizer. The crystallisation of sucrose in pure and impure systems was the study subject. Calcium chloride was utilized as impurity in this work. The resul
