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 m in diameter, 180 g. Prior to ball milling the amount of nacre tablets and geological aragonite was reduced to 15 wt with ultrapure water.

Physical properties of organic particulate UV absorbers

The particles were micronized in presence of a dispersing agent by means of a ball milling process. According to the energy input different particle sizes were produced in the range of 0.16 to 4 microm. In order to study even smaller particles, the sample with particle size 0.16 microm was fractionated further by centrifugation.
