Abstract: The fabrication technology of Na-β"-Al2O3 ceramic tubes by reaction sintering, i.e., by decom-position of the starting materials at 900℃ followed by reaction sintering and stepped annealing for phase transformation, was investigated. The Na-β"-Al2O3 tubes thus prepared have fine properties and the duplex microstructure can also be controlled in a certain degree.

Key words: Na-β"-Al2O3 ceranucs, reaction sintering, microstructure
