Aerosal Synthesis of Ceramic Powders

Flagan博士建议使用两种方法来研究高质量陶瓷粉末的合成：蒸汽前驱体方法，其中种子颗粒通过蒸汽和团簇沉积相结合的方式生长；以及电喷雾，以产生微小的液体前驱体液滴。实验和模拟研究将集中在团聚颗粒的致密化、团簇沉积颗粒的生长以及种子气溶胶反应器和电喷雾的放大技术。气相沉积和电喷雾形成气溶胶、团聚体的烧结以及相应的放大技术是制备具有工程结构和性能的陶瓷粉末的关键问题。

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.
