| description | Thermal diffusivity, a of a medium is the thermophysicaJ property which
determines the speed of heat propagation by conduction during changes of
temperature with time. The measurement of thermal diffusivity can be carried
out at room temperature by photoflash method, which employs a high intensity
camera flash as the excitation source. In this paper, Sr1
_
xLaxSn0
3
ceramics
doped with different compositions of La (x = 0.1, 0.4, 0.6, 0.8, 1.0) was
investigated for their thermal diffusivity. The thermal diffusivity values varied
from 0.44 x 10-2
- 1.15 X 10-2 cm2/s corresponding to x = 0.1 to x = 1.0. The
morphology and structure of Sr1
_xLaxSn03 ceramics were analysed from SEM
and XRD measurements to support the thermal diffusivity behaviour. |
