Abstract 9803539 A. Weimer, University of Colorado at Boulder The objective is to develop a model for exothermically reacting aerosol particle generation mechanisms (coagulation, coalescence, and deposition) with application to combustion nitridation synthesis of fine ceramic particles, and to validate the obtained model with data from ceramic particle formation experiments. An aerosol reactor shaped as a tube will be constructed with capabilities to measure temperature and wall deposition along the tube. The P.I. will collaborate in modeling with Prof. S. Pratsinis (University of Cincinnati). Several ideas are advanced for generation of ceramic composite particles and redirection of thermophoretic deposition from the reactor wall. It is expected that an improved model for particle growth and structure, and a reduction of wall deposition in manufacturing of advanced ceramic powders by exothermic processing The research has relevance to high temperature synthesis of nonoxide ceramic material in aerosol flow reactors. ***

摘要9803539 A. Weimer，科罗拉多大学博尔德分校科罗拉多的目标是开发一个模型，应用于燃烧氮化合成细陶瓷颗粒的气溶胶颗粒生成机制（凝聚，聚结和沉积），并验证所获得的模型与陶瓷颗粒形成实验的数据。 一个气溶胶反应器的形状为一个管将建造有能力测量温度和壁沉积沿着管。 私家侦探将与S. Pratsinis（辛辛那提大学）。 几个想法是先进的陶瓷复合颗粒的产生和重定向的热泳沉积从反应器壁。 本文的研究结果对气溶胶流动反应器中高温合成非氧化物陶瓷材料具有一定的指导意义。 ***
