| Abstract: | The smaller the size of the raw material particle was, the better the characteristic of the gassensor was. This paper introduced a new type of material that was applied to the fabrication of nanometer SnO2 powder by the solgel process. The particle size of SnO2 powder made by this way was lessthan 10nm. That the temperature and time of the heathg treatment had effect on the size was studiedand a further analysis by theory was given. At the same time. The particle size of SnO2 powder wasmeasured and analyzed by means of TEM, BET and XRD, and the result was given. |
