先进材料疑固实验室 Liquid/Solid interface Laboratory of Advanced Materials Solidification The thermodynamic driving force of crystal growth is the difference in the Solid Liquid Gibbs free energies of the solid and liquid,△Gv. The barrier of crystal growth is the free energy increase,Q,in transferring G atoms across the solid/liquid interface. Its magnitude is dependent on the nature of the solid/liquid interface. This free energy barrier is also often called the activation energy for crystal growth. 上浒充通大学 SHANGHAI JIAO TONG UNIVERSITYLiquid/Solid interface The thermodynamic driving force of crystal growth is the difference in the Gibbs free energies of the solid and liquid, ∆GV.
