Composite powders consist of alumina and silicon carbide of different particle size ( i.e 3.7 um, 12.5 um, 17.5 um and 50 um) were mixed for 2 1/2 hours in a tumbler mill. compacts were obtained by cold pressing the composite powder at 200 MPs and sintering in argon atmosphere at 600 C for 5 hours. results showed that size of silicon carbide powder has a considerable effect on the composite properties. As a conclusion, the use of finer silicon carbide powder has increase the density, hardness, modulus of rupture and electrical resistivity of the composite. Repository Staff Only: item control page
