Preparation of Sinter-Active Silicon Carbide Powders

摘要

Pressureless sintering of silicon carbide powders permits the production of more complicated components than is possible with existing pressure-sinter methods. This report describes the production of sinter-active SiC powders and the influence of process parameters in the pressureless sintering of SiC into high-density materials. It is shown possible to produce sinter denities of CH-110 or 95 percent with powders produce from pyrolysis of methyl silane.
