| 中文摘要 | 本研究以化學共沉法使用二乙基草酸酯為共沉劑,成功的合成了極細之 具Bi-2212相結構高溫超導粉末之前趨物,同時以檸檬酸凝膠法及固態法等數種製 程方法合成具Bi-2212相結構之高溫超導體,並以熱重分析法(Thermal Gravimetric Analysis;TGA)、差式掃描熱量測定法(Di由rential Scanning Calorimetv;DSC)、紅外光 吸收光譜(Infrared:IR)、掃描式電子顯微鏡(Scanning Electron Microscope;SEM)、X 光粉末繞射(PowderX-ray Diffaction;XRD。)及磁性量測來探討數種製程之反應機 構,並由其結果比較具優缺點。 |
| 英文摘要 | This research will be using homocoprecipitation to prepare the superconductorsofBi-2212. From a nitric acid solution that contains starting nitrates and use diethyloxalate as a precipitant, we had obtained a high quality superconducting power. In themeanwhile, we had also used gel and solid method to prepare the superconductingpowers. The superconducting powers will be studied by XRD (Powder X-ray diffraction),TGA( Thermal gravimetric analysis ), IR ( Infrared ), SEM ( Scanning electron microscope ),SQUID. |
