Abstract

Ceramics based on yttrium aluminum garnet doped with ruthenium ions were synthesized. Ceramic samples were obtained by non-reactive sintering of nanocrystalline powders formed by chemical coprecipitation. The results of XRD and EDX analysis indicated that the yttrium-aluminum garnet matrix can accommodate up to 0.5 àt.% of ruthenium cations without the formation of secondary phases or impurities. Minor deviations from the stoichiometry of the composition did not hinder the incorporation of ruthenium into the structure of yttrium aluminum garnet. In addition, changes in the valence of the sintering additive had no effect on the solubility of ruthenium ions in the ceramic material.

钌离子在钇铝石榴石结构中溶解度极限的测定

制备了钌离子掺杂钇铝石榴石陶瓷。采用化学共沉淀法对纳米晶粉末进行非反应烧结制备陶瓷样品。XRD和EDX分析结果表明，钇铝石榴石基体可容纳0.5 àt。%的钌阳离子而不形成二次相或杂质。化学计量学上的微小偏差并不妨碍钌进入钇铝石榴石的结构。此外，烧结添加剂的价态变化对钌离子在陶瓷材料中的溶解度没有影响。
