A study was conducted to demonstrate fragment-based design of NbRuB as a new metal-rich boride superconductor. The samples were synthesized by arc melting elemental starting materials in a water-cooled copper crucible under an argon atmosphere using a tungsten electrode. The starting materials, niobium, ruthenium, and boron were weighed in the NbRuB stoichiometric ratio pressed into pellets, and arc melted for 10 s. The products were turned and melted several times to ensure good homogeneity. The as-cast arc-melted NbRuB sample was examined by powder X-ray diffraction for identification and phase purity.
