章节摘录
版权页: 插图: Diffusion is the distribution of a substance by ran-dom motion of individual particles.It is due to the presence of a gradient of the chemical potential in the system.A gradient is defined as the increment of a func-tion in an infinitely short distance,along the direction of the most rapid variation of the function.Diffusion always reduces this gradient.Molecular diffusion is ob-served in viscous media and at low supersaturations,as well as in the growth of crystals,in thin films of liquids,and in capillaries.In molecular diffusion the transport of matter to a crystal is slower than under other diffusion conditions.The thickness of the boundary layer increases with time and the concentration gradi-ent gradually decreases.Therefore,the rate of growth decreases with time.The time interval during the for-mation of a boundary diffusion layer represents the non-steady-state condition.During this initial period,the rate of growth varies considerably.The thickness of the boundary layer depends on the difference between the densities of different parts of the solution (i.e.,on the rate of growth of a crystal),the viscosity of the so-lution,and the dimensions of the crystal.The presence of the boundary near the crystal and the orientation of the crystal itself affect the nature of the convection cur-rents and the thickness of the boundary layer at different crystal faces. Forced Convection Forced convection is produced by the action of exter-nal forces such as the forced motion of a crystal in the solution.There is no basic difference between forced and natural convection.When the velocity of motion of a solution with respect to a crystal is increased,the thickness of the boundary layer increases and the supply of matter to a face of the crystal increases.
