Abstract
【解決手段】 銀イオンを含有する水性反応系に還元剤含有水溶液を添加して銀粒子を還元析出させることにより、500℃における収縮率が5〜15%、600℃における収縮率が10〜20%、平均粒径が5μm以下、タップ密度が2g/cm3以上、BET比表面積が5m2/g以下の球状銀粉を製造する。
【選択図】 なし
Description
銀イオンとして12g/Lの硝酸銀溶液3600mLに、工業用のアンモニア水300mLを加えて、銀のアンミン錯体溶液を生成した。この銀のアンミン錯体溶液に水酸化ナトリウム60gを加えてpHを調整した後、還元剤として工業用のホルマリン90mLを10秒で加えた。その直後に、ステアリン酸エマルジョン0.5gを加えて銀のスラリーを得た。この銀のスラリーをろ過、水洗した後、乾燥して銀粉を得た。この銀粉に高速攪拌機で表面平滑化処理を施した後、分級により8μmより大きい銀の凝集体を除去した。
500℃における収縮率(%)=(L50−L500)/L50×100
600℃における収縮率(%)=(L50−L600)/L50×100
ここで、L50、L500、L600はそれぞれ、試料温度が50℃、500℃、600℃におけるペレット状の銀粉試料の長さ(mm)である。
[実施例2]
銀イオンとして12g/Lの硝酸銀溶液3600mLに、工業用のアンモニア水180mLを加えて、銀のアンミン錯体溶液を生成した。この銀のアンミン錯体溶液に水酸化ナトリウム1gを加えてpH調整した後、還元剤として工業用のホルマリン192mLを15秒で加えた。その直後に、ステアリン酸0.1gを加えて銀のスラリーを得た。この銀のスラリーをろ過、水洗した後、乾燥して銀粉を得た。この銀粉に高速攪拌機で表面平滑化処理を施した後、分級により11μmより大きい銀の凝集体を除去した。
銀イオンとして12g/Lの硝酸銀溶液3600mLに、工業用のアンモニア水150mLを加えて、銀のアンミン錯体溶液を生成した。この銀のアンミン錯体溶液に還元剤として工業用のヒドラジン13mLを2秒で加えた。その直後に、オレイン酸0.2gを加えて銀のスラリーを得た。この銀のスラリーをろ過、水洗した後、乾燥して銀粉を得た。この銀粉に高速攪拌機で平面平滑化処理を施した。
