Formation of SnO2 gels from dispersed sols in aqueous colloidal solutions
Transparent SnO2 gels were obtained from SnCl4 aqueous solution. The sol formation from tin oxihydroxy peptization in different concentrations and by electrolyte addition in solution was measured. It was verified that the ...
Effect of cobalt(II) oxide and manganese(IV) oxide on sintering of tin(IV) oxide
Additions of 0.5 to 2.0 mol% of CoO or MnO2 onto SnO, promote densification of this oxide up to 99% of theoretical density. The temperature of the maximum shrinkage rate (TM) and the relative density in the maximum ...
Non-parabolic intergranular barriers in tin oxide and gas sensing
(American Institute of Physics, 2012-07-30)
Chemoresistive properties of crystalline solids strongly depend on the concentration of stoichiometric defects. In the case of tin oxide, oxygen vacancies are a case in point of such kind of defects. We address the problem ...
Study of SnO2 gels by Eu3+ fluorescence spectroscopy
Eu3+ fluorescence spectroscopy was used as a probe to study the changes in local arrangements of tin oxyhydroxide precipitate → sol → gel → glass conversion. Electronic transition intensities and 5D0 excited state lifetime ...
Densification of Mn-doped tin oxide films by conventional heating and microwave heating treatment
Mn(II) doped SnO2 thin films used for shielding fluoride glasses against corrosion were investigated by x-ray absorption spectroscopy (EXAFS and XANE)S at the Sn and Mn K-edges. The effect of firing treatment on the ...
Transport and sensors properties of nanostructured antimony-doped tin oxide films
(Elsevier B.V., 2006-12-05)
Tin oxide thin films doped with 7 mol% antimony oxide multilayer were prepared by the polymeric precursor method. Morphological characterization revealed films with round-shaped grains, nanometric size (similar to 13 nm), ...
Polyol-mediated synthesis of ultrafine tin oxide nanoparticles for reversible Li-ion storage
(Elsevier B.V., 2007-05-01)
A simple, cheap and versatile, polyol-mediated fabrication method has been extended to the synthesis of tin oxide nanoparticles on a large scale. Ultrafine SnO2 nanoparticles with crystallite sizes of less than 5 nm were ...
