Superconductor is a material that can conduct electricity or transport electrons from one atom to another with no resistance. This means no heat, sound or any other form of energy would be released from the material when it has reached "critical temperature" (Tc), or the temperature at which the material becomes superconductive. There are 2 types of superconductors which are the type 1 superconductor consists of basic conductive elements that are used in everything from electrical wiring to computer microchips. Meanwhile type 2 superconductor is composed of metallic compounds such as copper or lead. The prime aim for this research is to develop the Bi-2223 superconductor using the solid-state reaction method and irradiate it with electron radiation (beta radiation). Molar ratio of Bi2O3, PbO, Sr2CO3, CaCO3 and CuO were mixed according to its ratio into composition of Bi(Pb): Sr:Ca:Cu = 1.6(0.4):2:2:3. The mixture was ground and heated in a tube furnace with free air flow at temperature of 800 K for 24 hours to remove impurities and form the Bi-2223 oxide. The resultant powder will be calcinate and sintered to get the original sample of the superconductor Bi-2223. Electron irradiation on the samples will be carried out using a beam of 3 MeV, current measurement of 10 mA and radiation dose of 100 kGray. The irradiation will be conducted using the EPS-3000 electron-beam accelerator at the Malaysian Nuclear Agency. The structural, morphological, and phase formation will be investigated using X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). The texture coefficient, TC (hkl) of Bi-2223 superconductor will be evaluated from the X-ray diffraction patterns and the crystallite size of Bi-2223 superconductor grains will be estimated from the Scherrer equation. Moreover, based on the SEM results it can be concluded as the Electron Irradiated sample has caused a slight degrading effect. Based on the XRD result it is confirmed that the pure phase of Bi-2223 was developed with the Co-phase of Bi-2212 and the pure phase of Bi-2223 did not destroy after the electron radiation. Texture coefficient calculated and average crystallite size has been proved that the electron irradiated sample hold the higher value compared to the non-electron irradiated sample. Finally, results obtained shows that electron irradiated sample is better compared to the non-electron irradiated sample. 2023-05-03T15:03:10Z 2023-05-03T15:03:10Z 2019-10 https://irepository.uniten.edu.my/handle/123456789/20504 application/pdf
