| Summary: | In this paper, the undoped and Sm doped BSCCO superconducting ceramic
samples prepared at various sintering times (i.e. 24, 48 and 100 hours) were
investigated for their thermal diffusivity. The thermal diffusivity value was
measured at room temperature using photoflash technique. The excitation
source and detection system consisted of a high intensity camera flash and Ktype
thermocouple. The measured thermal diffusivity value was found to be
highly dependent on dopant concentration but not on sintering time. In this
study, the surface morphology observed using Scanning Electron Microscopy
(SEM) strongly supports the thermal diffusivity results. |
