Oxide Ceramic Fibers by the Sol-Gel Methods

Abstract

Sol-gel processing has many advantages over traditional powder based ceramic processing. These advantages include better homogeniety, higher purity and low temperature synthesis. Additionally, the sol-gel process is the only low temperature process available to make high temperature stable oxide fibers. Most of these fibers cannot be formed by drawing via the traditional melt method. This report includes research conducted on the preparation of lanthanum chromite fibers. Lanthanum chromite's high temperature stability was enhanced by coating with alumina. Additionally, a test high temperatures. Several commercial fibers, including alumina fibers were tested with this rig.
