The relative density improved in proportion to the press pressure, and 82.9-95.3% was obtained. When the hot-press pressure is 28.17MPa, the sintered compact has a relative density of 95.3%, Vickers hardness 15.2GPa, flexural strength 216MPa, fracture toughness 2.06MPa・m1 / 2, Young's modulus 204GPa, shear modulus 84.8 GPa, surface roughness Ra 297nm and electric conductivity 7.67MS/m. It is characterized by having high electrical conductivity.}, pages = {1--8}, title = {ホットプレスLaB₆セラミックスの機械的及び電気的特性}, volume = {56}, year = {2022} }
