MgB2 fabrication by diffusion-controlled three layered (B-Mg-B) technique

► For technological applications, high quality MgB2 should be fabricated. ► The used fabrication technique influences significantly the superconducting properties of the MgB2 system. ► High-pressure environment for fabrication of the MgB2 system is required. ► MgB2 was successfully fabricated through diffusion-controlled three-layered (B-Mg-B) material.
