English Abstract

In this study, an experiment entitled "Synthesis and Characterization of Y-Ba-Cu-O High-Temperature Superconductor" was designed for General Chemistry Laboratory to introduce students the experimental skills of inorganic materials chemistry. An YBa_2Cu_3O_(7-δ) high-temperature superconductor was synthesized through solid-state reaction of appropriate amounts of Y_2O_3, BaCO_3, and CuO. The asprepared product showed diamagnetism at liquid nitrogen temperature. This experiment on the synthesis of superconductor was carried out by 62 freshmen from Department of Chemistry. National Taiwan University. 97% of the students in the class could successfully synthesized the compound exhibiting diamagnetism. Questionnaire surveys revealed that most students were highly interested in this experiment which is considered appropriate to be included into General Chemistry Laboratory Courses. Furthermore, experimental techniques, such as grinding. calcination. sintering, pressing. and determination of diamagnetism were well demonstrated in this experiment.
