Metal oxide nanoparticles today are utilized for many established and novel applications. They can be fabricated in high control and reproducibility via solvent-based approaches such as the nonaqueous sol-gel synthesis, which has been presented for a number of systems in the last years. The industrial use of these methods however is retarded by a lack of detailed process-related knowledge for these methods. The interrelation between process parameters and the particle properties is not generally known, and also the mechanisms and kinetics of particle formation are only understood for a few single systems. This research project involves systematic process studies for the nonaqueous synthesis of metal oxide nanoparticles, utilizing two model systems to obtain detailed knowledge on the influence of the process parameters on particle formation. Thereby, not only the molecular mechanisms are investigated, but also the particle formation, ripening and agglomeration. In the last phase of the project, the experimental data are utilized for the generation of a model based on population balances that can predict the processes of primary and secondary particle formation and reflect the influence of the process parameters.

如今，金属氧化物纳米颗粒用于许多已建立和新颖的应用。它们可以通过基于溶剂的方法（例如非水溶胶 - 凝胶合成）在高控制和可重复性中制造，该方法在过去几年中已针对许多系统提出。然而，这些方法的工业用途因缺乏与这些方法相关的过程相关知识而阻碍。过程参数与粒子特性之间的相互关系通常不知道，而且粒子形成的机制和动力学仅在几个单个系统中才能理解。该研究项目涉及用于金属氧化物纳米颗粒非水合成的系统过程研究，利用两个模型系统获得有关过程参数对粒子形成的影响的详细知识。因此，不仅研究了分子机制，还研究了颗粒形成，成熟和团聚。在项目的最后阶段中，实验数据用于基于人口平衡的模型生成，该模型可以预测主要和次要粒子形成的过程并反映过程参数的影响。
