| Abstract: | Pressureless sintered Al_2O_3/SiCp composite was prepared using Y_2O_3 as sintering additive added in ceramics powders with coating means. When the particles were coated with Y_2O_3, the structure of green compacts was uniform and its density high. The maximum values of the relative density and strength reached 96.8% and 364 Mpa, respectively. |
