Abstract
Permanganate-containing pellets for gradual release or permanganate comprise an integrated body of a hydratable, self-curing cement in cured, hydrated form, and finely-divided particles of a water-soluble permanganate salt in substantially uniform distribution therein. The pellets are formed from a mixture of the permanganate salt, hydratable self-curing mineral cement, and water.
