Abstract: The SnO2 thin films were prepared by Sol-Gel technique anddip-coating method using colloidal particles derived from an inorganic salt（SnCl4.5H2O）as precursor.Well-crystallized SnO2 thin films were obtained about 600℃ after dehydration.When the content of SnO2 and the pulling rate are fixed there is a well linear relationship between the thickness of SnO2 thin films and the different viscosities of the dipping solutions.And when the content of SnO2 and PVA used as viscosity adjustment agent are fixed there is also a well linear relationship between the thickness of SnO2 thin films and the pulling rates.The mean slope of the straight lines is 0.58，which is well in line with the reported scale.The thickness（t）of SnO2 thin films and the pulling rates（v）of substrates from dipping solutions were correlated with an expression of t≈V0.58.
