Gas sensing materials of WO 3 +xwt%SiO 2 (x=0, 5, 10, 20) were prepared by means of a sol-gel method. The microstructure was characterized through XRD, AFM, XPS and surface area analyzer. The materials' NH 3 sensing properties were measured in conventional flow apparatus. It is observed that the nanosized monoclinic phase of WO 3 is formed and the grain size is decreased with the increase of SiO 2 . Being superior to the pure WO 3 element, the WO 3 +5wt%SiO sensing element gave the fairly good response to NH 3 above 350°C.
