Abstract: A silver powder mixture that is suitable for forming a conductive film on a surface of a member having stretchability, a method for producing the same, and a conductive paste using the silver powder mixture is provided. A silver powder mixture containing filamentous silver powder including spherical and filamentous parts and flaky silver powder having an average particle diameter of 1 ?m or more and 50 ?m or less and an aspect ratio, which is defined by a ratio of an average long diameter and an average thickness, of 1.5 or more is obtained by adding one kind or two or more kinds of a salt of copper and aluminum and ethylenediaminetetraacetic acid to a silver nitrate aqueous solution, for 60 seconds or more, and then adding a reducing agent containing one kind or two or more kinds of L-ascorbic acid, erythorbic acid, and salts thereof.

Abstract: To provide a conductive paste including: a filler containing a silver powder and a graphite powder; a polymer; and a solvent, where a 1%-weight-reduction starting temperature of the graphite powder, which is determined through a thermogravimetry-differential thermal analysis method, is 300° C. or more but 640° C. or less.

Abstract: At least one basic precipitant selected from the group consisting of NaOH, KOH, NH4OH, NH3, NH4HCO3 and (NH4)2CO3 is added to an indium salt solution, which contains 0.1 to 3 M of indium, in an adding time of not longer than 24 hours, while the solution is maintained at a temperature of 5 to 95° C. until the equivalent of the basic precipitant reaches an equivalent of 0.5 to 3. Then, a precipitate obtained from the solution by a solid-liquid separation is dried and calcined at a temperature of 570 to 780° C. in an non-oxidizing atmosphere which contains ammonia gas and water vapor.

Abstract: A Sn-containing In oxide in the form of needles or plates comprising particles having a major axis of 0.1 ?m or less and a minor axis of 0.05 ?m or less.

Abstract: To a hydrochloric acid solution containing In and Sn and which is held at 20° C., an alkali solution is added to adjust pH to 3; the temperature of the mixed solution is raised to 90° C. and the alkali solution is further added to adjust pH to 7.5. The resulting precipitate is recovered by filtration, dehydrated and dried to yield a Sn-containing In hydroxide; the hydroxide is put into a tubular furnace and fired in a nitrogen gas atmosphere containing water vapor and NH3 gas at 600°C. for 2 hours to produce a Sn-containing In oxide in the form of plates having a major axis of 0.041 &mgr;m, a minor axis of 0.025 &mgr;m and a major-to-minor axis ratio of 1.64.
