Aqueous ball milling of nacre constituents facilitates

Nov 15 2017 · The ball mill (MiniCer Netzsch Germany) was cleaned with HNO 3 and NaClO followed by intensive washing with ultrapure water. Wet grinding was performed at 28°C and 3000 r.p.m. using ZrO 2 balls (300 µm in diameter 180 g). Prior to ball milling the amount of nacre tablets and geological aragonite was reduced to 15 wt with ultrapure water.
