The resulting material is finely ground, at first in a mortar and then in a ball mill and subsequently washed repeatedly with water so as to remove halides and other soluble reaction products. The washed material is activated through three washings in hydrogen peroxide, 10% vol., and is eventually dried and further ground with a ball mill.
