抄録

The effect of additives on the densification and strengthening of titanium nitride (TiN) ceramics has been described. The additives studied were oxides (Al₂O₃, Y₂O₃ and MgO), nitrides (BN, AIN and Si₃N₄) and carbides (SiC and B₄C). The TiN compacts containing 5 and 10wt% additives were hot-pressed at 1950°C for 60min (except for Si₃N₄) in the ambient Ar gas of normal pressure. Additions of 10wt% Al₂O₃, 10wt% Y₂O₃ and 10wt% B₄C gave the relative densities of 97.4, 96.2 and 97.7%, respectively. The mechanical and electrical properties are as follows: 10wt% B₄C increased the hardness; 5wt% BN the flexural strength; 10wt% B₄C or 10wt% Y₂O₃ the values of fracture toughness (K_IC); 10wt% Al₂O₃ or 10wt% B₄C the Young's modulus and the rigidity; 10wt% B₄C the electrical conductivity. As a whole, 10wt% Al₂O₃, 10wt% Y₂O₃ and 10wt% B₄C additives contributed to both densification and strengthening. The most promising additive is 10wt% B₄C for TiN ceramics from the view point of relative density, mechanical and electrical properties, and prevention of grain growth.
