Dr. Flagan has proposed to investigate the synthesis of high quality ceramic powders using two approaches: vapor precursor routes in which seed particle are grown by a combination of vapor and cluster deposition, and electrospray to produce fine droplets of liquid precursors. The experimental and modeling research will focus on the densification of agglomerate particles, particle growth by cluster deposition, and scale-up techniques of seeded aerosol reactors and electrosprays. Aerosol formation by vapor deposition and electrospray, sintering of agglomerate, and corresponding scale-up techniques are critical issues for the production of ceramic powders with engineered structures and properties.

Flagan博士建议使用两种方法研究高质量陶瓷粉末的合成：蒸气前体路线，其中种子颗粒是通过蒸气和簇沉积的结合以及电喷雾生长的，以产生精细的液态液体前体。 实验和建模研究将集中于聚集颗粒的致密化，粒子生长通过簇沉积以及种子气溶胶反应器和电刺的扩大技术。 通过蒸气沉积和电喷雾形成气溶胶，集聚的烧结以及相应的缩放技术是生产具有工程结构和特性的陶瓷粉末的关键问题。
