Summary

Tin oxide powders with and without Sb as a dopant were prepared by coprecipitation from aqueous chloride solutions, A new technique called sol-gel coating was utilized to adjust the surface chemistry of Sb-doped SnO2 powders. Powders coated with a TiO2-SiO2-Na2O sol-gel composition sintered to almost theoretical density and very low resistivity when fired at 1350°Cfor 2 h. Thick films processed using coated Sb-doped SnO2 powders were very sensitive to ethyl alcohol, decreasing the resistance at room temperature by 900 ohms.
