The developed method of high-pressure synthesis (HPS) allows producing nanostructural highly dense material based on MGB₂, which possesses the highest superconducting and mechanical characteristics among the known world analogues, in the form of blocks that are suitable for application in SC electromotors and pumps. Additions of Zr can increase critical current density (j_c) of synthesized at 2 GPa and 750-800 °C MGB₂ in the same manner as additions of Ta or Ti, i.e. due to the absorption of impurity hydrogen forming the ZrH₂. The formation of ZrB₂ phase at higher synthesis …
