図1に、本発明による実施形態の銀被覆ボール10の断面図を示す。図1に示すように、本実施形態の銀被覆ボール10は、ボール状のコア1と、コア1を包囲するように設けられた平均粒径1nm以上50nm以下の銀超微粒子を含む被覆層2とを有している。
分散液Aは、約90質量%の銀超微粒子(平均粒径約3nmから約15nm)と約10質量%の溶媒とを含有する分散液である。分散液Aは、本実施形態で規定する銀超微粒子と溶媒との含有比率を満足していない。溶媒は、キシレンとトルエンのみからなり、トルエンよりもキシレンを高い比率で含有している。
分散液Bは、分散液Aに対し、キシレンを更に添加したものであり、約60質量%の銀超微粒子(平均粒径約3nmから約15nm)と約40質量%の溶媒とを含有している。分散液Bは、本実施形態で規定する銀超微粒子と溶媒との含有比率を満足している。
まず、直径0.75mmの銅コアを中性脱脂液506(石原薬品製)を用いて脱脂した(前処理)。具体的には、銅コアを中性脱脂液中に浸漬した(35℃で約5分間)後、室温下、純水で約3分間洗浄し、更に流水中で約1分間洗浄した。次いで、エタノール中に約2分間浸漬し、乾燥した。
実施例2の銀被覆銅ボールは、直径0.75mmの銅ボールの代わりに直径0.35mmの銅ボールを用いたこと以外は、前述した実施例1と同様にして作製した。実施例2の銀被覆銅ボールにおける銀超微粒子の被覆層の厚さは、約0.7μmである。
比較例1の銀被覆銅ボールは、分散液Bの代わりに分散液Aを用いたこと以外は、前述した実施例1と同様にして作製した。
図4および図5に、実施例1および比較例1の銀被覆銅ボールを実体顕微鏡で観察した写真を、それぞれ、示す。参考までに、図6に、銀被覆層を形成する前の銅ボールの顕微鏡観察写真を示す。
実施例1および実施例2の銀被覆ボール中に含まれるC(炭素)の量を、前述した高周波燃焼赤外線吸収法によって測定した。測定試料の質量は約0.2gである。
図8に、実施例1の銀被覆銅ボールのDTA曲線を示す。具体的には、銀被覆銅ボール(25mg)を大気中にて5℃/分の昇温速度で加熱したときのDTA曲線を測定した。参考のため、図9に、分散液AにおけるDTA曲線の結果を示す。
