Controlled Vapor Phase Nucleation and Growth of Nanometer- Sized Ceramic Oxide Particles

这一阶段的SBIR奖是为了探索一种产生微小陶瓷氧化物颗粒的新技术。将所需氧化物的金属盐与有机氧化物混合，雾化并燃烧。盐由于燃烧产生的高温而分解，蒸发，然后冷凝形成小颗粒。这样产生的颗粒将被分析其大小和团聚程度。这项技术在原则上与煤燃烧中形成细小灰粒的机理是一致的。然而，由于盐的选择、盐的浓度、有机液滴的大小和燃烧条件的不同，它应该更可控。

This Phase I SBIR award is to explore a novel technique for generating small ceramic oxide particles. A metal salt of the desired oxide is mixed with an organic, atomized, and combusted. The salt decomposes due to the high temperature generated by combustion, vaporizes, and then condenses to form small particles. Particle so generated will be analyzed for size and degree of agglomeration. This technique is identical, in principle, to the mechanism of forming small ash particles in coal combustion. However, it should be much more controllable due to the choice of salt, salt concentration, organic drop size, and combustion conditions.
