Abstract
The growth kinetics of the (001) and (110) faces of K2Co(SO4)2 · 6H2O and K2Ni(SO4)2 · 6H2O crystals in the kinetic mode has been in situ investigated for the first time by laser interferometry. The method used makes it possible to measure the slope p of the growing vicinal hillock and the normal growth rate R. The average step velocity ν = R/p as a function of supersaturation σ has been calculated based on these data. The kinetic coefficients of steps are determined. Some conclusions on the optimal growth conditions for crystals are drawn.
