Title: Preparation of tin compound sol
Inventor: SATO GORO
IPC: B01J13/00
Filed: 1986-02-08
Abstract: PURPOSE:To obtain a tin compound sol capable of forming a conductive film excellent in transparency, by hydrolyzing a tin compound to which water was added and subsequently adding a water-soluble org. solvent to the obtained hydrolysate before removing water therefrom under heating so as to adjust the same to a specific amount or less. CONSTITUTION:A hydrolyzable tin compound such as stannic chloride is dissolved in water to be hydrolyzed and a water-soluble org. solvent such as alcohols or dimethylsulfonamide is added to the obtained hydrolysate and water is subsequently removed therefrom under heating so as to be adjusted to 1.0wt% or less to obtain a tin compound sol wherein the tin compound is dispersed in the org. solvent. If the obtained sol is applied to a substrate comprising glass or ceramic and dried and baked, a transparent conductive film extremely excellent in transparency and having a reduced film thickness is formed. In order not only to control the resistance value of the obtained conductive film but also to enhance heat stability, a hydrolyzable antimony compound can be used along with the tin compound.
