Abstract
The pelletisation or granulation of a material or mixture of materials the or at least one of which is reactive in a liquid to produce a gas is improved by treating the reactive material prior to final compaction to form a coating thereon of a substance which is less soluble in the liquid than the reactive material. The preferred reactive material is calcium hydride and the preferred coating is calcium carbonate with or without calcium hydroxide.
