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

在该项目的一期工程中，试验了一种制备聚集度可控的纳米陶瓷氧化物颗粒的气溶胶新工艺。在第二阶段，将通过生产不同纳米尺寸的晶体材料(二氧化钛、氧化锆等)来延长这一过程。以及开发可靠的技术来控制聚集程度。调查将包括对连续工艺的研究，改善烧结特性的测试，以及对该工艺的经济评估。预计由该工艺生产的纳米陶瓷颗粒将在发动机零部件、机械零部件和高温燃气轮机中获得广泛的应用。

A new aerosol process for producing nanometer scale ceramic oxide particles with controllable degree of aggregation was tested in Phase I of this project. During Phase II, the process will be extended by generating different nanometer size crystalline materials (titania, zirconia, etc.) and developing reliable techniques to control the degree of aggregation. The investigation will incorporate a study of continuous processing, testing for improved sintering characteristics, and economical evaluation of the process. It is expected that the nanometer scale ceramic particles produced by the proposed process will find numerous applications in engine components, machine parts and high temperature gas turbines.
