Abstract
The present investigation of the rate of growth of crystals in different directions was originally suggested by a paper by G. Wulff on the velocity of growth and dissolution of crystal faces. Wulff carried out an extensive series of experiments with “Mohr’s Salt,” iron-ammonium sulphate, Fe(NH 4 ) 2 (SO 4 ) 2 . 6H 2 O, growing a crust of this salt on a nucleus of the less soluble isomorphous zinc-ammonium sulphate, Zn(NH 4 ) 2 (SO 4 ) 2 . 6H 2 O, which was introduced into a saturated solution of the former salt. He measured the thickness of the crust deposited on various crystal faces, and found it to vary for different forms. As the thickness of the crust deposited represented the amount of growth of each form, Wulff deduced numerical values for the velocity of growth of the forms developed, taking as unity the rate of growth of r {2 ¯ 01}, the slowest growing form observed.This publication has 0 references indexed in Scilit:
