Formation of SnO2 gels from dispersed sols in aqueous colloidal solutions
(1990-05-01)
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 ...

Drying of SnO2 hydrogels: effect of the electrolyte
(1992-12-01)
The effect of the electrolyte (NH+ 4, Cl-) on the drying of SnO2 hydrogels was investigated by linear shrinkage, mass loss, gravimetric thermal analysis and infrared spectroscopy. Results show that the drying mechanism for ...
Effect of electrolyte on the gelation and aggregation of SnO2 colloidal suspensions
(1992-12-01)
Electrolytes may modify the physical-chemical characteristics of colloidal particle interfaces in suspension, which can favour gel or aggregate formation. The influence of NH4Cl loading on the aggregation and gelation of ...

Sulfated tin oxide with macro- and mesopores controlled using an integrated sol-gel and surfactant template route
(2019-12-20)
Sulfated tin oxide was synthesized by a sol-gel process and pores were formed in the ceramic powders using Pluronic F-127 as a soft template. Sulfate ions linked to the tin oxide promoted the formation of acid sites on the ...
