Abstract

Piece-form materials which comprise 5-100% by mass calcium formate and 95-0% by mass additives and have particle sizes of 0.2-5 mm can be prepared from finely crystalline calcium formate and the additives by compression and, if necessary, subsequent comminution and/or fractionation to set the particle size.
