Abstract
We have studied the effect of heat treatment in an oxidizing medium and under vacuum on the properties of Russian-made silicon carbide fiber. The fiber has been characterized by a variety of physicochemical analysis techniques, including scanning electron microscopy, Raman spectroscopy, IR spectroscopy, and X-ray diffraction, before and after heat treatment under vacuum and in air. The kinetics of fiber oxidation in air have been studied in the range 900–1000°C. The activation energy for the oxidation process has been determined to be 72.0 ± 7.8 kJ/mol. The tensile strength of the fiber has been determined before and after heat treatment in different media. The results demonstrate that heat treatment under vacuum and in an oxidizing medium causes substantial degradation of the properties of the fiber.
期刊介绍：
Inorganic Materials is a journal that publishes reviews and original articles devoted to chemistry, physics, and applications of various inorganic materials including high-purity substances and materials. The journal discusses phase equilibria, including P–T–X diagrams, and the fundamentals of inorganic materials science, which determines preparatory conditions for compounds of various compositions with specified deviations from stoichiometry. Inorganic Materials is a multidisciplinary journal covering all classes of inorganic materials. The journal welcomes manuscripts from all countries in the English or Russian language.
