Surface defects and shape defects of ceramic fibers from refractory oxides

Abstract

The present article discusses ceramic fibers of refractory oxides used as the main components of heat-resistant refractory materials. Obviously, external defects affect the mechanical characteristics of refractory oxide ceramic fibers. In this regard, using optical and electron microscopy, the morphology of the surface of ceramic fibers was investigated, defects were classified, analysis was carried out, the causes of their occurrence were established and methods for their elimination were proposed.
