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.

这个第一阶段SBIR奖是探索一种新的技术， 小的陶瓷氧化物颗粒。 所需氧化物的金属盐， 与有机物混合、雾化并燃烧。 盐会分解 由于燃烧产生的高温， 然后凝结成小颗粒。 这样产生的粒子将 分析其大小和聚集程度。 原则上，这种技术与成形机制相同 煤燃烧中的小灰粒。 但是，它应该是多 由于盐的选择，盐浓度， 有机液滴尺寸和燃烧条件。
