| Abstract |
| Porous alumina based ceramics were fabricated by injection method, where alumina
powders were used as raw materials and solvent silicone resin was used as binder.
During the heat treatment process, an organic-inorganic transformation occurred in
silicone resin. The increase of heating temperature promoted the formation of mullite
phase when the temperature was higher than 1500oC. The weight loss of porous
alumina based ceramics was maintained at 5.7~5.9%. When the heating temperature
was 1500oC, porous alumina based ceramics showed the biggest shrinkage rate, lowest
apparent porosity and highest bending strength.
