The influence of the amount of F-agent on the characteristics of nanoparticles (NPs), instant phase stability, the NPs shape and the process of NP crystallization are discussed. The structural reorganisation in F-modified amorphous xerogel aggregates leads to the formation of anisotropic-shaped crystallites under the crystallization of such xerogel. The kinetic parameters of crystallization are estimated. It was shown the main mechanism of crystalization is crystal growth controlled by interface reaction and bulk nucleation occurs with constant number of nuclei. The change of mechanism from 3-dimensional growth for pure zirconia to 2- or 1-dimensional growth for modified systems with the increasing of F-amounts is observed. It reflects the change of the morphology of crystal from sphere for pure zirconia to parallelopipedon and needle shapes for F-modified zirconia with high F-content. The increasing of E_a value of F-modified xerogels in comprison with an unmodified system is observed.

讨论了F剂的添加量对纳米颗粒（NPs）特性，瞬时相稳定性，NPs形状和NP结晶过程的影响。F-改性无定形干凝胶聚集体中的结构重组导致在这种干凝胶的结晶下形成各向异性形状的微晶。估计结晶的动力学参数。结果表明，结晶的主要机理是受界面反应控制的晶体生长，并且在成核数量不变的情况下发生了整体成核。观察到随着F量的增加，从纯氧化锆的3维生长到改性系统的2维或1维生长的机理变化。它反映了晶体的形态从纯氧化锆的球形到平行六面体的形状以及高F含量的F改性氧化锆的针形变化。E的增加_一个在comprison F-改性干凝胶与未修饰系统值是观察。
