摘要：
Thick films of bulk tin oxide powder were observed to be less sensitive to polluting, hazardous and inflammable gases. So, nanostructured ZrxSn(1-x)O(4) powder was synthesized by disc type ultrasonicated microwave assisted centrifuge technique. Thick films of nanostructured pure Zr(0.75)Sn(0.25)O4 powder were fabricated by screen printing technique. These films were surface functionalized by SrO2 for different intervals of time followed by firing at 450 degrees C for 30 min. The surface morphology, chemical composition, crystal structure, electrical and gas sensing performance of the unmodified and surface functionalized nanostructured Zr(0.75)Sn(0.25)O4 powder by SrO2 have been investigated by FESEM, E-DAX, XRD, etc.
