Title: | Grain growth in sol-gel derived alumina-zirconia composites | Authors: | Srdić, Vladimir Savić, D. |
Issue Date: | 1998 | Publisher: | Springer Link | Journal: | Journal of Materials Science | Abstract: | Grain-growth kinetics in sol-gel derived alumina zirconia composites, containing 20 wt% ZrO2 stabilized with 0, 3 and 6 mol% ceria have been examined. The growth of alumina grains was effectively retarded by zirconia particles and a lake of abnormal growth was evident. Coupled grain growth was observed, but only if the required minimal sintering conditions (i.e. minimal sintering density) were reached. Measured grain-growth exponents indicate that the grain-boundary diffusion-controlled growth is probably the dominant rate-controlling mechanism in this system. © 1998 Chapman & Hall. | URI: | https://open.uns.ac.rs/handle/123456789/12747 | ISSN: | 00222461 | DOI: | 10.1023/A:1004307908928 |
