ABSTRACT:
A method of making an inorganic salt-hydrogen peroxide complex includes the following steps: (a) mixing the inorganic salt with sufficient water for a time sufficient to form a soft paste, (b) mixing the paste with an aqueous hydrogen peroxide solution to form a hydrogen peroxide-containing paste, and (c) drying the hydrogen peroxide-containing paste. A hydrate method of making Na.sub.4 P.sub.2 O.sub.7.3H.sub.2 O.sub.2 includes the steps of: mixing sodium pyrophosphate decahydrate solid with an aqueous solution of hydrogen peroxide having a concentration of less than 30%, and drying the mixture. Compositions of matter include K.sub.2 HPO.sub.4.3H.sub.2 O.sub.2, KH.sub.2 PO.sub.4.H.sub.2 O.sub.2 Ca.sub.2 P.sub.2 O.sub.7.nH.sub.2 O.sub.2, Ca.sub.2 P.sub.2 O.sub.4.nH.sub.2 O.sub.2, Na.sub.2 SO.sub.4.nH.sub.2 O.sub.2, K.sub.2 SO.sub.4.nH.sub.2 O.sub.2, Na.sub.2 SiO.sub.3.nH.sub.2 O.sub.2 and Na.sub.2 SiO.sub.7.nH.sub.2 O.sub.2.
