| ABSTRACT |
|
Titanium Cabride powders were prepared by the self-propagating high temperature synthesismethod in air from the mixture of metal titanium powder and carbon powder. The result are as follows : 1. The conversion effciency of higher than 95% can be obtained and the lattice constant value of the product was 4.322$AA$. 2. The combustion mode, velocity and temperature of combustion wave was photographed using high-speed camera, and showed steady-state, velocity of 15.414mm/sec at 250$0^{circ}C$. 3. The relative density and MOR strength of TiC sintered at 180$0^{circ}C$ for 90 minutes by hot-pressing under the pressure of 200kg/$textrm{cm}^2$ were 95% and 395MPa, respectively. |
