The Structurization of Aluminum Oxide Composite Ceramics Involving Products of Iron Oxide Reduction by Nanosized Nonstoichiometric Silicon Carbide

Abstract

The paper studies the structurization of aluminum oxide ceramics sintered with additions of a synthesized fine SiC-Fe 2 O 3 powder alloy. The fine-grained powder alloy particles promote the densification of the alumina matrix. The mechanical properties of the composites are examined. The material obtained is tested as a cutting tool.Keywords: solid solution of carbon in silicon carbide, aluminum oxide, iron oxide, sintered iron ore concentrate, stishovite, cutting tool.
