Ball milling of copper powder only

2.2. Mechanical Treatment of Copper Powder For the grinding of the copper nanoparticles, a mixer mill (Retsch MM 400) having two stainless steel with 50 cm3 grinding jars and two stainless steel grinding balls (vol-ume: ∼8.2 cm3, diameter: 25 mm) were applied. The mill was operated using constant ball/sample weight ratio (100), and 120 min
