Synthesis of pure Bi-2223 superconductor via co-precipitation method / Nur Humaira Yasmin Mohd Alimi

Superconductor has long be an interest of researches as the potential it possesses. Superconductor is a material that has zero resistance when reaching its critical temperature which give unlimited electrical conductivity theoretically. The aim of this research is to study the synthesis of pure Bi2Sr2CaCu2O8+x or BSCCO-2223 superconductor via co-precipitation method. BSCCO or Bismuth Strontium Calcium Copper Oxide is a high temperature superconductor which also extensively studied. The co-precipitation method was chosen is because the method is not widely used by researchers to synthesis superconductors sample due to its tedious steps. No addition is added to the sample as to achieve the aim of this project and only pure Bi-2223 was synthesized. Characterization of the sample was supposedly carried out by XRD, ACS and TGA. XRD is used to observe the physical microstructure of the sample while ACS is used to determine the critical temperature of the sample and TGA is used to analyze the decomposition reactions which allow quantitative composition analysis. However none were carried out due to some restrictions. The sample went through until the sintering process but the end result shown that it was severely burnt. No explanation to why this is happened but it may be because of excessive polishing used during palletizing process.
