heal.abstract Properties of materials synthesized from Mg and B and sintered from MgB2 using high-pressure (2 GPa) and hot-pressing (30 MPa) at 700- 1100 degrees C are discussed. The influence of Ta, Ti and Zr additions on the material structure and properties was studied. The average grain size of 15-37 nm was observed for materials produced under a pressure of 2 GPa. For high-pressure synthesized MgB2, the highest critical current densities known from literature have been obtained. Dispersed inclusions of higher borides with the stoichiometry close to MgB12 and MgB7 can act as pinning centers in the magnesium diboride material manufactured using high pressure and hot pressing. en
