Preparation: |
first mechanically crushed to pieces of ~1 cm2 and a couple of millimetres thick, then either treated with liquid N2 in cooling-heating cycles or further treated by mechanical crushing using a mill. The powder was then dry-sieved into different size fractions. During the mechanical treatment and the sieving, the finest fraction was repeatedly removed so that only the larger mineral particles were treated. In order to remove ultra-fine particles, the chlorite powder was ultrasonically washed in ethanol. |
