【 摘 要 】

Combustion of the metal, magnesium, and aluminum oxides based multicomponent systems in the revolving reactor has been studied. Mullite, corundum, and spinels have been synthesized out-of-furnace by means of the self-propagating high-temperature synthesis. Both the composition and structure of the synthesized ceramic materials have been identified using certain correlation of the initial components and centrifugal acceleration rate. The conditions of synthesizing tubular ceramic materials by combustion of the magnesium-aluminum-aluminum oxide-nickel oxide system have been determined. The tube composition has been represented by corundum and spinel.
