Abstract
Porous Al2O3 ceramics with different SiC contents were successfully prepared through preceramic polymer process following by sintering at 1500â¯Â°C at N2 atmosphere, where ball-shape Al2O3 powders and preceramic polymer silicone resin were used as the matrix and the binder. According to the SEM, XRD and elemental analysis, it was found that C-nanowires were formed in the gap between grains in sintered samples, which was formed by the organic-inorganic transformation of silicone resin at N2 atmosphere. The existence of SiC was beneficial for the formation of C-nanowires. With the increase of SiC content in the samples, the porosity had no evidently change, however, the bending strength increased from 23â¯MPa to 50â¯MPa.
