Growth kinetics of the {10.4} faces of (NaNO3)

In this paper, we focus on the measurement of the normal growth rates (R104) of {10.4} faces of nitratine (NaNO3) single crystals under isothermal conditions in the temperature interval 288-297.5 K in order to unravel the rate determining steps during crystal growth, depending on the hydrodynamic co...
