Pengaruh Penambahan Carbon Nanotubes pada Pembuatan Kawat Superkonduktor Mgb2

Abstract

Research on the effect of CNT addition on manufacturing of MgB2 superconducting wire has been done. MgB2 is superconducting material which has a critical temperature about 39K and potentially as superconducting wire applications. Addition of CNT about 5%, 10% and 20% on MgB2 prefixed by weighing MgB2 powder (~100 mesh) and CNT powder (20 – 40 nm). Then, mixed and grinded with mortar agate for 30 minutes. The grinded results inserted into SS304 tube, and process of wire rolling and wire drawing until 3,0 mm. Characterization using X-Ray difractometer to determine the phase, SEM was used to determine the phase morphology, and superconductivity by Cryogenic magnet. The Results show that cricital temperature, Superconducting wire MgB2 without addition of CNT is 39.58K and Superconducting wire MgB2 with addition of CNT is 29.16K. Addition of CNT affected superconductity of MgB2.
