Abstract

Dust-free alkaline earth peroxides are obtained by mixing alkaline earth peroxides with a compacting aid and dry-compacted in a compactor, for example, a roller press. Examples of suitably useful compacting aids include sodium bicarbonate, cellulose, magnesium montanate and cross-linked silicone compounds.
