• 中文摘要： 本研究是利用刮刀成型法,將Bi/sub 1.6/ Pb/sub 0.4/Sr/sub 2/Ca/sub 2/Cu/sub 3.6/O/sub x/初燒粉末製成厚膜。而後採用熔融淬火及退火處理,可將厚膜成功地放置在氧化鎂基板上。並獲得最好的退火溫度、時間及氧分壓條件,以使厚膜的110K相含量最大,且其微結構具有高方向性,臨界電流達到2.6*10/sup 3/A/cm/sup 2/。
• 英文摘要： Tapes with precursor composition of the Bi/sub 1.6/ Pb/sub 0.4/Sr/sub 2/Ca/sub 2/Cu/sub 3.6/O/sub x/ were fabricated in this present work by doctor-bladed casting. Green tapes were laid on the MgO ( 100) substrate, followed by the melt-quenching process and annealing treatments. The effects of annealing temperature, time and oxygen partial pressure on the formation of 110K phase in resulting thick films were investigated. Excellent films could be obtained with a high volume-percentage of 110K phase, a highly c-axis oriented microstructure and a critical current density of 2.6*10/sup 3/A/ cm/sup 2/ at 77K and zero field.
