 note = {application, Experiments have been performed to investigate the effective additives of titanium nitride (TiN) ceramics for the densification and the strengthening. The additives include Al_2O_3, Y_2O_3 and MgO as oxide ceramics, BN, AIN and Si_3N_4 as nitride ceramics, and SiC and B_4C as carbide ceramics. The TiN ceramics containing 5 and 10 wt. % of additives was hot-pressed at 1950℃×60 min (except the case of Si_3N_4) in the ambient Ar gas of normal pressure. As a experimental result, 10% Al_2O_3 and 10% Y_2O_3 showed the relative densities of 96.6, 96.1%, respectively. The mechanical and electrical properties are as follows: 10% B_4C increased the hardness; 5% BN did the flexural strength; 10% B_4C and 10% Y_2O_3 did the toughness of K_<IC>; 10% Al_2O_3 and 10% B_4C did the Young's modulus and the rigidity; 10% B_4C decreased the resistivity, i. e., increased the electric conductivity. As a whole, the 10% Al_2O_3, 10% Y_2O_3, 10% AIN and 10% B_4C additives contributed to both the densification and the strengthening. In these additives, the most promising additive was seemed to be 10% B_4C for TiN ceramics from the view point of the density, the mechanical properties and the grain growth.},
