  • Patent number: 10773961
    Abstract: To provide a silver-coated graphite mixed powder including: silver-coated graphite particles each including a graphite particle and silver coated on a surface of the graphite particle, where when a solution obtained by dissolving the silver-coated graphite mixed powder in nitric acid is analyzed through inductively coupled plasma (ICP) emission spectrometry, an amount of silver is 5% by mass or more but 90% by mass or less, an amount of tin is 0.01% by mass or more but 5% by mass or less, and an amount of zinc is 0.002% by mass or more but 1% by mass or less.

  • Patent number: 7820138
    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.

  • Publication number: 20030030036
    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.
