The Dutch physicist Heike Kammerlingh Onnes discovered superconductivity in 1911, when he studied the resistivity of solid mercury at cryogenic temperatures using the liquid helium found as a refrigerant. Bismuth Strontium Calcium Copper Oxide (BSCCO) is the very first high-temperature superconductor system with no unusual components. It was first prepared in 1988 and is one of the most important cuprate compounds where superconductivity occurs through copper oxide. The primary objectives of this research are the synthesis of the Bi-2223 superconductor by a coprecipitation process. The samples are then irradiated with neutron radiation. Two Solutions were formed and it was labeled as Solution A and Solution B. Then, the Solution A were formed synthesized by the co-precipitation powders with nominal composition of Bi1.6Pb0.4Sr2Ca2Cu3Ox mixed with acetate acid. Solution B was formed by stirring the oxalic acid in 320ml of di-ionized water, H2O with 480ml of isopropanol until it is dissolved. Solution A and Solution B were mixed together and dried. The dried powder was subjected to pre-calcination at 740oC for 12 hours in air to remove the remaining volatile materials. The pre-calcined powder was then grounded using pestle and mortar for 30 minutes and calcined at 845oC in air for 24 h to ensure the elimination of the Bi-2201 phase. The samples were then sent to thermal neutron flux quantification for 3 hours which is equal to 2x1615n/cm2 neutron fluency using the TRIGA PUSPATI Reactor.Using scanning electron microscopy (SEM) the structural, morphological, and phase structure was investigated. Based on the findings of the SEM it can be inferred that the neutron irradiation produced a minor deterioration on the sample effect's micro-structure and texture. A four point cryogenic device is used to evaluate the electrical properties determining the critical temperature, Tc. 2023-05-03T14:59:22Z 2023-05-03T14:59:22Z 2020-09 https://irepository.uniten.edu.my/handle/123456789/20378 application/pdf
