✦ Synopsis

On the basis of calculations of the bond strength (of constituent chemical bonds that form during crystal growth process) and expanded capacity of low Miller index planes in KH 2 PO 4 (KDP) and NH 4 H 2 PO 4 (ADP) crystals, the ideal crystal morphologies and interactions between crystal surfaces and ethanol molecules are comprehensively studied. Our present results show that the crystallites morphology are mainly determined by the bond type, number, direction and strength, as well as the additive ingredient ethanol. Ethanol molecules may strongly affect ADP and KDP crystallites morphology by interacting with hydrogen bonds at crystal surfaces.
