Title:
METHODS OF PRODUCING SILICON CARBIDE FIBERS, SILICON CARBIDE FIBERS, AND ARTICLES INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2012/048066
Kind Code:
A3
Abstract:
Methods of producing silicon carbide fibers. The method comprises reacting a continuous carbon fiber material and a silicon-containing gas in a reaction chamber at a temperature ranging from approximately 1500°C to approximately 2000°C. A partial pressure of oxygen in the reaction chamber is maintained at less than approximately 1.01 x 10 Pascal to produce continuous alpha silicon carbide fibers. Continuous alpha silicon carbide fibers and articles formed from the continuous alpha silicon carbide fibers are also disclosed.
