【 摘 要 】

Al - ZrW2O8pseudo alloys were synthesized by free sintering of Al - ZrW2O8powder mixture. Influence of sintering time on the structure formation of the pseudo alloys obtained was investigated. It has been shown that during sintering process zirconium tungstate decomposes into constituent oxides and re-synthesis of zirconium tungstate proceeds through intermediate stage - formation of WAl12and ZrAl3intermetallic compounds.
