Nano-sized SnO2-B2O3-P2O5 particles were synthesised by an aerosol flame deposition (AFD) technique. Single or multi-component amorphous oxide nano particles (soot) were synthesised by supplying metal halide sources such as chloride in the form of gas into an oxy-hydrogen flame. The fine powder obtained was a mixture of crystalline tin oxide and an amorphous phase of B2O3 and P2O5, resulting in a highly dispersed structure with nano-scale interfaces. According to the XRD results, the as-prepared materials seemed to have a semi-amorphous structure and SEM images showed that the average particle size was < 60 nm. The relationship between the structural modification of the tin-based composite oxide and the conductivity as a function of the composition was investigated. 12 refs.
