在这项工作中，镧orthobates掺杂锑，钙，或两者都已合成和研究。通过热重研究分析了所研究材料的吸水率。结果表明，铌酸镧系质子导电陶瓷的水化热力学与其它质子导电陶瓷的水化热力学有很大的不同。发现了所研究体系的吸水率与有效受体掺杂之间的关系，并对吸水率关系的能量学进行了讨论。
In this work, lanthanum orthoniobates doped with either antimony, calcium, or both have been synthesized and studied. The water uptake of the investigated materials has been analyzed by means of thermogravimetric studies. The results show the difference between the thermodynamics of hydration between the lanthanum orthoniobate system and other proton conducting ceramics. The relation between the water uptake and effective acceptor doping for the investigated system has been found, and the energetics of the water uptake relation are discussed.
