Zinc peroxide is an oxidizer capable of sustaining energetic mixtures.
It was once used as an antiseptic, because it introduces large amounts of oxygen into the environment of anaerobic bacteria.
Zinc peroxide is a white to bright yellow solid, insoluble in water. It has a density of 1.57 g/cm3. Zinc peroxide decomposes explosively if heated to 212 °C.
Zinc peroxide is sold by dentistry suppliers, usually 60% pure.
A suspension of zinc oxide in hydrogen peroxide will eventually turn a shade of yellow as ZnO2 is formed but it does not go to completion in dilute peroxide and separating the two insoluble oxides formed this way is impossible. Some energetic properties can still be observed with this mixture however.
- Flash powder
Zinc peroxide is irritant to eyes, nose and mouth. Proper protection should be worn when handling the compound.
Zinc peroxide should be stored in closed containers, away from moisture and acidic vapors.
Zinc peroxide can be neutralized with acids.
