摘要

Hot isostatic pressing with glass encapsulation (pressure, 200MPa; temperature, 1000 ℃ over 200 min; cooling under pressure) was used to synthesize bulk MgB_2 with diameters up to 20 mm and thicknesses up to 10 mm from MgB_2 powder. A sharp superconducting transition was measured at 38.5 K. This method can be scaled to larger sample sizes and complex shapes. The data for density, microhardness, fracture toughness and sound speed for bulk magnesium diboride are presented. Ball milling the powder results in a more homogeneous final microstructure with a higher resistivity and with a similar superconducting transitions.
