摘要：

In this article, we investigate the influence of powder granulometry on the superconducting properties of (Ba0.6K0.4)Fe2As2 tapes manufactured using the Powder-In-Tube (PIT) technique. Variations in particle size distribution, which we successfully modulated through planetary ball milling and meticulous powder synthesis process, can affect the packing of the powders inside the metallic sheath and the mechanical deformation process of the samples, impacting their transport properties, as known for other practical conductors. The comparison among PIT tapes realized with a consistent fabrication route made with powders with different granulometries is reported, highlighting the effects on the transport property performances.
