 note = {application/pdf, In order to understand the characteristics of B₄C monopoly, the effects of hot-press (HP) pressure and Ar inert atmospheric pressure on the mechanical / electrical properties of pure B4C powder compact were investigated using the HP method. The sintering temperature was constant at 1950 ° C, and the sintering time was 3.6 ks. When the press pressure was increased, the densification occurred rapidly and the relative density reached 99.3% even at a low HP pressure of about 23.4 MPa. Furthermore, when the press pressure was 31.2 MPa, a relative density of 99.9%, a flexural strength of 502 MPa, and a hardness of 38.5 GPa were obtained. By using the HP method, B4C is able to obtain high properties and a smooth surface (mirror surface) by the HP sintering without adding a sintering aid.},
