In the case of 1, hydrogen peroxide is added to the thus obtained dispersion in an amount of 0.1 to 2 mol, preferably 0.5 to 1.5 mol, per gram atom of zinc. As hydrogen peroxide, commercially available hydrogen peroxide solution with a concentration of 30 to 35% may be used.The addition rate of hydrogen peroxide is not particularly limited, but considering the reaction efficiency of hydrogen peroxide, It is best to add hydrogen peroxide relatively quickly, and then gradually add it slowly as the reaction progresses. However, the rate of addition of hydrogen peroxide itself does not affect the decomposition temperature of the final product, zinc peroxide, and the Zn07 content The difference is only a few percentage points.

When hydrogen peroxide is added to a dispersion of a zinc compound such as zinc oxide, the temperature of the system increases by several tens of eels51 due to an exothermic reaction.
The reaction temperature is adjusted to be within the range of 0 to 80°C.The higher the reaction temperature, the more coarse particles are likely to be formed in the final product, zinc peroxide powder, and these coarse particles can be used for various plastics. When used as a foaming aid, it not only causes voids, but also causes some open cells to be mixed in with the closed cells, which is undesirable.Therefore, the temperature of the reaction liquid should be below about 40 to 45°C. In particular, in order to strictly reduce the amount of coarse particles, it is desirable to keep the temperature at 30 to 35°C.
