Fabrication of TiC-Ti Porous Materials by Combustion Synthesis
TiC-Ti porous materials have been successfully prepared using combustion synthesis in this paper. Adiabatic temperature of Ti-C and Ti-C-TiC systems was calculated. As to the Ti-C system, the studies show that when the ratio of C/Ti is the range of 0.5-0.6, the pressure of protecting atmosphere is 2-4 MPa, and the density of green compact is about 60%, the synthesized sample exhibits excellent properties such as porosity of 40%, volume density of 2.6 g/cm3, compressive strength over 4 MPa. Pore size is as large as 5-25 µm and the majority pores belong to interconnected pore.
