中文摘要 | 合成多成份單一相且每一結晶粒均化學計量之單晶粉末,是研究上與工業上之難 題。 本研究利用熱水系統技術探討合成此類單晶型粉末可行性。 研究對象定為 (Pb,La)(Zr,Ti)O �陘中� (Pb0.91,La0.09)(Zr0.65,Ti0.35) (9/65/35)。 本研究先以化學 共沈技術將四種元素成份離子並存於共沈膠中,使此多成份做原子級的混和,置在反應器中 藉類構造反應合成此一單晶型粉末。研究重點為觀察起始膠塊粒徑大小與合成之單晶型粉末 之特性關係,並找出最有利之製程條件。 |
英文摘要 | The preparation of a high-purity multi-component oxide powder of monophase and stoichiometry for each crystallilte provides an intriguing challenge to the laboratory and the industry. The possibility is performed by the synthesis of (Pb0.91La0.09)(Zr0.65Ti0.35)O �� (PLZT-9/65/35) powders using the hydrothermal system techniques. Gels containing stoichiometic Pb:La:Zr:Ti cations which coprecipitated chemically and presumably having atomic scale mixing were used as the starting materials. Emphasis were placed on examing the relationships between the gel particles and the characteristics of the crystallites (particles) frzomed by the hydrothermal synthesis. Finally the proper synthesis conditions were discussed. |
