Effect of NaNO₃ as Enhancer on YBa₂Cu₄O₈ Superconductor Phase Formation via Solid State Technique with Heating at Ordinary Oxygen Pressure

Abstract:

YBa₂Cu₄O₈has emerged as better choice in superconducting application thank to it strong thermal stability. High pressure techniques had been employed for the preparation of YBa₂Cu₄O₈but it might costly and/or inconvenient. Several research groups had showed that the YBa₂Cu₄O₈ can also be prepared by conventional solid state method with heating at 1 atm oxygen pressure; however the phase formation processes are yet brief and clear. This work infiltrated the phase formation processes in preparing the YBa₂Cu₄O₈under solid state method with heating at 1 atm oxygen pressure. The effectiveness of the use of sodium nitrate as an enhancer was brought to light by the experiment results. Significant YBa₂Cu₄O₈phases were successfully synthesized.
