中文摘要 | 近年來,由於ZNP型陶瓷材料(以NaZr�烈�記�漪陞N表)具有低熱膨脹、離子導電、 鐵電等性質,吸引了許多研究,包括合成方法、結構分析、及性質用途等。一般的合成方法 以固相法為主,因其具有方便及過程簡單等優點,不過固相法合成的粉末常會有第二相的產 生。 因此, 本研究針對 NZP 型材料中的 CaZr �� P �� O �瞗B SrZr �� P �� O �瞗B 及 BaZr �� P �� O �瞗A以化學共沉法來尋求合成單一相的最佳條件。 實驗結果顯示,較低的 溶液濃度、較慢的溶液滴入速率、鹼性及高溫的混合環境等,均有利單一相的合成。 |
英文摘要 | NZP family of ceramic materials, NaZr�烈�記�榮s prototype, possessing interesting properties of low thermal expansion, ionic conduction, and ferroelectricity, has drawn research interests in synthesis, structure analysis, and property applications recently. Most synthesis applied solid-state reaction method for its convenience and simple processing steps. However, second phases usually occurred. This research applied chemical co-precipitation method on the synthesis of CaZr �� P �� O ��, SrZr �� P �� O ��, and BaZr �� P �� O ��, seeking optimum processing conditions in order to produce single phase NZP materials. Experiment results showed that low solution concentration, slow solution mixing speed, and basic and high temperature mixing environment were favored in forming single phase materials. |
