摘要: 利用化學共沉淀法制取鋯酸鑭(La₂Zr₂O₇,簡稱LZ)和La₂O₃-CeO₂-ZrO₂(簡稱LCZ)熱障涂層噴涂粉,采用電感耦合等離子體光譜儀(ICP-AES)對粉的化學成分進行分析,用X射線衍射儀分析LZ,LCZ的物相組成,用差式掃描量熱法研究粉的高溫相穩定性.結果表明:LZ,LCZ粉均為燒綠石結構;高溫下LZ,LCZ無明顯相變.

Abstract: Lanthanum zirconate (La₂Zr₂O₇, LZ) and La₂O₃-CeO₂-ZrO₂(LCZ) powders for thermal barrier coatings were prepared by coprecipitation. The chemical composition of the powders were analyzed by means of Inductively Coupled Plasma-Atomic Emission Spectrometry (ICP-AES). Crystallographic phases were determined by X-ray diffraction technique. Differential Scanning Calorimetry (DSC) was used to analyze the phase stability at high temperatures. The results showed that both LZ and LCZ powders kept the pyrochlore structure and there were no phase transformations for LZ and LCZ at high temperatures.
