Cd2SnO4-its sol-gel preparation and materials properties
- 60 Downloads
Cd2SnO4 powder has been synthesized through acrylamide sol-gel route for the first time. The gelation-calcination steps have been studied. Morphological examination of the network matrix and the calcined products has been done through SEM. XRD shows the orthorhombic structure of the Cd2SnO4 powder obtained. Arrhenius plots yield activation energies of 0·01 and 0·61 eV for the low and high slope regions, respectively. A semiconductor to metal transition is observed in the range 210–225°C.
KeywordsCadmium tin oxide sol-gel acrylamide
