| Abstract: |
| We got aluminum sol by using aluminum isopropoxide,nitric acid and distilled water.After that,zirconia powder was added into the aluminum sol to get the composite slurry.By using such methods as DTA,XRD and sedimentation, the performance of the composite slurry was analyzed. Results show that the pH value for the slurry should be controlled around 2, and the appropriate molar ratio of aluminum isopropoxide to distilled water is 1∶ 80. Furthermore, the suggested content of zirconia powder in the slurry is 85% to 90% by volume, and the proper temperature for the composite slurry to be sintered is about 830℃ . |
