High-Temperature Synthesis of Superconducting MgB2 Materials in a Centrifuge

Abstract

There is a wide variety of superconducting materials, but only a few of them are suitable for practical industrial use, and one of the most promising superconductors is MgB2. Its main advantages are a critical temperature close to 40 K, which allows for operation in a cryogenic environment, low cost of precursors, and the ease of manufacture. In this paper, we attempted to obtain superconducting materials based on magnesium diboride in a new way by using a high-temperature centrifuge and then investigated how centrifugal acceleration could affect the superconducting characteristics of the materials in a greater way during combustion synthesis. As a brief result of this research, it was found that the value of centrifugal acceleration affected the critical current density (Jc = 1.4 A/cm2) of the MgB2 composites, although it did not considerably impact the critical transition temperature of the MgB2 materials (remained at around 37.5–38 K).
