【 摘 要 】

The superconductor of Y-124, Y259, and Y-358 phases has been successfully synthesized using the wet-mixing method. The compounds of Yttrium Oxide, Barium Carbonate, Cuprum Oxide, and Nitric Acid as a digesting agent have been used. The sample was prepared by calcination at 600 °C for 3 hours and subsequently sintering at 850 °C for 5 hours. The synthesis of Y-124, Y-259, and Y-358 phases were processed using a wet-mixing method. The phases were assumed to have the same initial temperature of crystalline growth around 800 °C. The a and b-axis lattice parameters decreased by the increase in Y atoms. On the other hand, the c-axis lattice parameter increased by adding Cu atoms. The volume of unit cells increased with the addition of Ba and Cu atoms. It was also found that LIBS was very effective in detecting the atoms contained in the sample and predicted in the percentage of the atoms in the sample.
