本文在前文的基础上进一步讨论了固溶胶粒的生长和施主原子浓度等问题。本文先讨论施主原子浓度的特性,证明它与杂质浓度无关;在胶粒生长后期,施主原子浓度可以近似地用杂质临界浓度表示。施主原子与胶粒的“平衡”,并不意味着系统的自由能处于极小,而是继续缓慢下降,因而在“平衡”条件下测得的施主原子浓度具有一定的零散度。进而从原子扩散角度描述小胶粒缩小和大胶粒生长的物理图象,并讨论了粒子的线度生长速率;接着讨论胶粒有一定分布时的情况。 具体讨论了KCl,KBr,KI和NaCl的临界状态,及其有关参量E_β,β。再后就热凝聚和光凝聚等问题进行一些讨论。
Based on the above, this article further discusses the growth of solid sol particles and donor atoms concentration and other issues. In this paper, we first discuss the characteristics of donor atomic concentration and prove that it is independent of the impurity concentration. At the late stage of colloidal particle growth, the donor atomic concentration can be approximated by the critical concentration of impurities. The “equilibrium” between the donor atom and the micelle does not mean that the free energy of the system is extremely small, but continues to decline slowly, so that the concentration of donor atoms measured under “equilibrium” conditions has a certain degree of scatter. Then the physical image of small particle size reduction and large particle growth is described from the perspective of atomic diffusion. The linear growth rate of particles is also discussed. Then, the situation of the particle distribution is discussed. The critical states of KCl, KBr, KI and NaCl are discussed in detail, and the related parameters E_β and β are discussed. Then some discussion on the issues of thermal aggregation and photocondensation.
