【Abstract】 TiB₂ceramics were sintered by hot pressing technique at different temperature with TiB₂ceramic powers, which are prepared by self-propagating high-temperature synthesis. They mechanical properties and microstructures were studied. The results showed that the relative density, hardness and bending strength of TiB₂ceramics increased quickly at first and then slowly with increasing temperature,and that their electrical conductivity also improved.更多还原
