MIXTURE FOR PREPARING COMPOSITE MATERIALS, PROCESS FOR PREPARING CERAMIC COMPOSITE ARTICLES, ELECTRIC HEATING ELEMENT AND THE CERAMIC COMPOSITE ARTICLE

摘要

Electrical heating elements and related articles having oxidation resistance at high temperatures, produced by a method involving micropyretic synthesis. A composition subjected to micropyretic synthesis comprises a filler material, a reactive system capable of undergoing micropyretic synthesis, and (optionally) a plasticizer or extrusion agent. The method of preparation of articles includes slurry techniques, plastic extrusion, slip casting, or coating.
