  • Silver-coated graphite particles, silver-coated graphite mixed powder and production method therefor, and conductive paste
    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.
    Type: Grant
