Aqueous ball milling of nacre constituents

15.11.2017· 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.
