- Abstract
- Core densification in superconducting wire is highly desirable for obtaining high performance super-conducting wires. Since voids hinder current flow in the superconducting core and they directly affect electrical property. In this study, we proposed a magnesium powder blending to regulate the porous properties. Our study delved deeper into the relationship between various particle parameters (such as particle size and distribution), impurities (MgO and Mg(OH)2), superconducting transition temperature, and current carrying capacity for MgB2 superconducting wires. We found a significant correlation between these factors and the porous properties. In particular, the blending of raw powders having spherical shape enables tuning of morphological structures and crystallinities inside cores of the power-in-tube processed MgB2 wires, resulting in superior superconducting properties. Our finding provides in-depth insights of methodological approaches towards more widespread use of superconducting materials and their appli-cations.
