Nanocomposite Zn2SnO4/SnO2 powder was
obtained by solid state synthesis from homogenized
starting nanopowders of ZnO and SnO2, mixed in the 1:1
molar ratio, structurally and morphologically characterized
using X-ray diffraction (XRD) and Scanning Electron
Microscopy (SEM). Thick film paste was made by adding
organic vehicles to the obtained powder. Three to five
layers (layer thickness approx. 12 µm) were screen printed
on alumina substrate with small test PdAg electrodes and
fired at 600oC for 30 minutes. SEM analysis confirmed formation of a porous structure suitable for humidity sensing.
Impedance response was studied at the working temperatures of 25 and 50oC in a humidity chamber where the
relative humidity (RH) was 30-90% and measured frequency 42 Hz – 1 MHz. With increase in film thickness the overall
sensor impedance increased. It reduced at 100 Hz from 36 to 0.25 MΩ (60 µm), from 23.4 to 0.25 MΩ (48 µm) and from
6.8 to 0.02 MΩ (36 µm) at 25 oC, while at 50 oC and ...also 100 Hz it reduced from 14 MΩ to 0.72 MΩ (48 µm) for RH 30 and
90%, respectively. The response (8 s) and recovery (10 s) was fast, showing that this nanocomposite has potential for
application in humidity sensing.
