Gas Sensing Properties of Pure and Cr Activated WO3 Thick Film Resistors
Thick films of WO3 (Tungsten Oxide) were prepared by screen-printing techniques. The surfaces of the films were modified by dipping them into an aqueous solution of Chromium Oxide (CrO3) for different intervals of time, followed by firing at 550 oC for 30 min. The gas sensing performance of the pure...
