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被用于许多已建立的和新颖的应用。它们可以通过基于溶剂的方法以高控制性和再现性制造，例如非水溶胶-凝胶合成，其在过去几年中已被提出用于许多系统。然而，这些方法的工业应用由于缺乏这些方法的详细工艺相关知识而受到阻碍。工艺参数和颗粒性质之间的相互关系通常不是已知的，并且颗粒形成的机制和动力学也仅针对少数单个系统被理解。该研究项目涉及金属氧化物纳米颗粒的非水合成的系统工艺研究，利用两个模型系统，以获得详细的知识，对颗粒形成的工艺参数的影响。因此，不仅研究了分子机理，而且还研究了颗粒的形成、成熟和团聚。在项目的最后阶段，实验数据被用于生成基于粒子数平衡的模型，该模型可以预测初级和次级粒子形成的过程，并反映工艺参数的影响。
