ABSTRACT:
A pellet of potassium superoxide, as the oxygen-yielding chemical, with an additive of catalyst material for stimulating the release of oxygen is improved by providing a concentrated addition of the catalyst material on the surface of the pellet; this permits a uniform release of oxygen during the entire period of the use of the pellet. With the pellet, oxygen is split off as required at the very outset of breathing with the breathing apparatus and a release of oxygen in excess of demand as use continues is avoided. A pellet of this type includes a compressed core body containing substantially potassium superoxide and surrounded by a compressed jacket made of highly catalyzed potassium superoxide material.
