Bi1.6Pb0.4Sr2Ca2Cu3O10+δ with the addition of carbon nanotubes (CNT) and TiO2 have been synthesized using solid state reaction method with the repeated sintering process. 0.1 wt % of CNT and 5 wt% of TiO2 have been added lớn analyze the effect on the synthesizing of 2223 phases. The samples were analyzed using XRD (X-ray diffractometer) và SEM (Scanning Electron Microscopy). Based on the XRD results, 2223 và 2212 were formed. The addition of CNTs & TiO2 reduced the intensity of 2223 phases. This is due lớn the addition of CNTs và TiO2 as an impurity & prevent the formation of the phases. Also, the repeated sintering process led to the increase of 2223 phase, and the decrease of 2212 phase. However, the repeated sintering process in the B-CNT & B-TiO samples eliminates the impurities phase thus increasing the volume fraction 2223 và decreasing the volume fraction 2212. Based on morphological structure through SEM observation, the addition of CNT in the Bi(Pb)-2223 samples formed longer plates with large porosity spaces while the addition of TiO2 formed clumps on the Bi(Pb)-2223 morphological structure. However, the repeated sintering process improves the morphological structure of B-CNT và B-TiO becomes increasingly denser & the smaller porosity space.

Telah dilakukan sintesis Bi1,6Pb0,4Sr2Ca2Cu3O10+δ dengan penambahan CNT (carbon nanotube) dan penambahan TiO2 menggunakan metode reaksi padarã dengan proses sintering berulang. Penambahan CNT sebesar 0,1 %berat dan TiO2 sebesar 5 %berat dan sintering berulang dilakukan untuk mempelajari pengaruhnya terhadap pembentukan fasa 2223 beserta pengotornya, dan mempelajari perubahan morfologi Bi1,6Pb0,4Sr2Ca2Cu3O10+δ. Bi1,6Pb0,4Sr2Ca2Cu3O10+δ yang dibuat dianalisis dengan XRD (x-ray diffractometer) dan SEM (scanning electron microscopy). Berdasarkan hasil XRD, penambahan 0,1 %berat CNT dan TiO2 sebesar 5 %berat pada superkonduktor Bi(Pb)-2223 diketahui menghasilkan fasa 2223, fasa 2212, dan juga fasa pengotor. Namun proses sintering berulang mampu mengurangi fasa impuritas, meningkatkan frakham mê volume 2223, serta menurunkan fraksi volume 2212. Berdasarkan pengamachảy struktur morfologi melalui SEM, penambahan CNT padomain authority superkonduktor Bi(Pb)-2223 membentuk serpihan memanjang dengan ruang porositas yang besar sedangkan penambahan TiO2 membentuk gumpalan padomain authority struktur morfologi Bi(Pb)-2223. Proses sintering berulang mampu memperbaiki struktur morfologi B-CNT dan B-TiO menjadi semakin rapat dan ruang porositas yang semakin kecil.
