PURPOSE: To prevent deterioration of quality of peroxide of divalent metal due to decrease of effective component with the lapse of time by incorporating a phosphorus component to peroxide of a divalent metal using phosphoric acid, condensed phosphoric acid, or their salt.
CONSTITUTION: At leat one phosphorus component selected from phosphoric acid, condensed phosphoric acid, or their salts is(are) incorporated into peroxide of a divalent metal. The peroxide of a divalent metal to be used is peroxide of Mg, Ca, Zn, etc. Suitable stabilizer is orthophosphoric acid, pyrophosphoric acid, (tri, tetra)-polyphosphoric acid, (tri, tetra)metaphosphoric acid, or their salts of Li, Na, K, H, NH4, Mg, Ca, Zn, etc. The phosphorus component to be contained in the stabilized peroxide is adjusted to 0.1W15wt% expressed in terms of P2O5.
