Abstract

The simple and inexpensive technique to synthesis nano crystalline tin oxide powder has been reported in this work. The nano crystalline tin oxide powder has been derived from stannic chloride, prepared through fine crystallization in liquid phase. Tin oxide powder has been characterized using SEM, TEM & XRD techniques which revealed crystal size around 13 nm. The slurry blobs deposited on alumina substrate of the powder thus prepared have been studied for sensing response of ethanol at various temperatures. The observations revealed that the material prepared is self-binding whereas commercial tin oxide powder required binders for sensor applications. Sensing response of nano particles of tin oxide deposited on alumina substrate has been investigated it was found very significant even without catalyst. These properties may have been attained by the prepared material due to the shift in the nano-scale range..
