• 中文摘要： 本文旨在證明球形之含鑭之氫氧碳酸鹽膠體微粒可在水熱條件下成功地以尿素為沈澱劑加以合成。同時實驗數據也顯示微粒之形態與其組成有關。而後者可藉由合成反應條件予以控制。對含鑭之球形微粒而言,若在水熱環境下老化過久,則仍將轉變為棒狀粒子。
• 英文摘要： It has been successfully demonstrated that spherical lanthanum hydroxycarbonate colloids can be synthesized under proper hydrothermal conditions using urea as the precipitant. It is also shown that the particle morphology may be related to its compositions, which in turn depends upon the reaction conditions and the aging time. In the present reaction system, all spherical precipitates will eventually transform into crystalline and rodlike particles if they are aged for a long period.
