Crystal growth morphology
WebCrystal growth is a surface-controlled phenomenon in which solute molecules are … WebApr 1, 2001 · Experimental morphology of ibuprofen crystal grown from ethanol and ethyl acetate. The growth rates of crystal faces grown in ethanol are all of the same order of magnitude. Therefore, the ibuprofen crystal is quite isometric. On the other hand, crystals grown from ethyl acetate result in thin elongated platelets.
