Abstract
- We investigate the influence of the grain size on the thermal diffusivity of pure Al[sub 2]O[sub 3] ceramics by using mirage effect. Results show that the value of thermal diffusivity decreases with increasing grain size, when the grain size of the sample is smaller than 200 nm, and the value of that increases with increasing grain size when the grain size is larger than 200 nm. The detailed experiments, the results, analyses, discussions are presented in this paper. © 2001 American Institute of Physics. [ABSTRACT FROM AUTHOR]
