Abstract
The effect of varying in sintering duration on superconductivity properties and microstructure of Tl 1212 were systematically studied. The main purposes of this study are to produce a sample of thallium-based system with nominal composition Tl₀.₈Cr₀.₂Sr₂Ca₀.₈Cu₂O₇ and to study the effect of varying in time duration at sintering on superconductivity properties and microstructure of Tl-1212. The procedure of methodology has two parts which are preparation of Tl-1212 using COP method and characterizations process such as Tc and SEM. The results are discussed in relation between critical temperature and microstructure. Tc for samples heated at 4, 6 and 8 minute is 92K, 81K and 83K respectively. The micro structures for sample heated for 4 minutes have a smooth surface than the samples that heated for 6 and 8 minutes which has a rough and not homogenous grains size. The appropriate sintering time is 4 minutes in order to achieve a homogenous structure.
