摘要
Abstract
In order to attain porous TiB_2-TiC multiphase ceramics, reactive sintering was carried out at different temperature to study the effect of temperature on the density, air permeability and mechanical properties of porous TiB_2-TiC multiphase ceramics. XRD was used to analysis phases composition of the sinters. The result indicates that TiB_2 and TiC are the final products when reaction finishs at 1 300℃ . With the rising of sintering temperature, the density and transverse rupture strength of all the specimens increase all the while, maximum aperture and the gas permeability decrease gradually. The porous TiB_2-TiC multiphase ceramics were prepared by sintering at 1 700℃ for 1h and its density,open porosity and transverse rupture strength at room temperature are 3. 2g/cm~3,29. 5% ,120MPa, respectively.关键词
