Plasma Processing of Advanced Ceramic Powders

PIs提出用等离子体合成技术制备极细碳化物和硼化物颗粒。他们建议使用改进的先前开发的非转移电弧等离子体流反应器，对与这些颗粒产生相关的反应动力学、传热传质、成核和生长动力学进行基本理解。一旦获得这些细颗粒，它们将被表征为通过烧结和热等静压颗粒产生的强度，硬度和韧性。pi进一步建议建立一个能够描述这些等离子体系统中的成核和生长现象的理论模型。

Abstract for Patrick R. Taylor / University of Idaho / CTS-9220252 The PIs propose to produce very fine carbide and boride particles by the techniques of plasma synthesis. They propose to develop a fundamental understanding of the reaction kinetics, heat and mass transfer, and nucleation and growth kinetics associated with the generation of these particles using a modified previously developed non-transferred arc plasma flow reactor. Once these fine particles are obtained, they will be characterized as to their strength, hardness, and toughness produced by the sintering and hot isostatic pressing of the particles. The PIs further propose to develop a theoretical model capable of describing the nucleation and growth phenomena in these plasma systems.
