反应烧结法制备Na-β”-Al_2O_3

Preparation of Na-β-Al2O3 Ceramics by Reaction Sintering Method

研究了Na-β"-Al2O3陶瓷管制备的反应烧结法，即在900℃分解初始组成，而后快速反应烧结和分阶段退火转相的工艺．制备的Na-β"-Al2O3管具有良好的性能，双重显微结构也在一定程度上得到控制．

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.
