Usage

Description

Zinc peroxide is a white powder containing 45-60% ZnO2 and the balance ZnO. It is a solid compound with properties similar to magnesium peroxide. The commercial product is a pale yellow powder containing about 55% ZnO2 and 9% active oxygen. It is stable in dry air but loses its oxygen in moist air and on heating. It decomposes rapidly above 150°C and decomposes in acids, alcohol, and acetone. It is insoluble in water but can be decomposed by it.

Uses

Used in Rubber Industry:
Zinc peroxide is used as an accelerator in rubber compounding and as a curing agent for synthetic elastomers. It enhances the processing and performance of rubber products by accelerating the vulcanization process and improving the rubber's properties.
Used in Pharmaceutical and Medical Applications:
Zinc peroxide is used as a deodorant for wounds and skin diseases. Its antimicrobial and antifungal properties help in reducing odor and promoting healing.
Used in Aesthetics:
Zinc peroxide has been applied in various settings, from medicine to aesthetics, where its properties can be utilized for different purposes, such as skin care products or treatments.

Air & Water Reactions

Slowly decomposed by water.

Reactivity Profile

Zinc peroxide dissolves in dilute acid, liberating hydrogen peroxide [Merck 11th ed. 1989]. Noncombustible but accelerates the burning of combustible material. If the combustible material is finely divided, the mixture may be explosive. Mixtures with combustible material can sometimes be ignited by friction or contact with moisture.The hydrated material (of indefinite composition) explodes at 212°C. Mixtures with aluminum or zinc powder burn brilliantly [Mellor 1940. v. 4, 530].

Health Hazard

TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Fire may produce irritating and/or toxic gases. Toxic fumes or dust may accumulate in confined areas (basement, tanks, hopper/tank cars, etc.). Runoff from fire control or dilution water may cause pollution.

Fire Hazard

May explode from friction, heat or contamination. These substances will accelerate burning when involved in a fire. May ignite combustibles (wood, paper, oil, clothing, etc.). Some will react explosively with hydrocarbons (fuels). Containers may explode when heated. Runoff may create fire or explosion hazard.

Safety Profile

Systemic toxicity is similar to zinc oxide. Flammable when SYN: ZINC SUPEROXIDE 212.. Can react.iolently with A. and Zn. Very dangerous, wdl react with water or steam to produce heat. Vigorous reaction with reducing materials. When heated to decomposition it emits toxic fumes of ZnO. See also PEROXIDES and ZINC COMPOUNDS.

A simple and green approach for preparation of ZnO2 and ZnO under sunlight irradiation

A green approach is developed for sol-gel synthesis of ZnO and ZnO2 through photochemical reaction under sunlight irradiation. The component and structure of the sol and powders are systematically analyzed, and the reaction equations are deduced and the fabrication mechanisms are discussed. It is found that the ZnO2 powder is obtained when sintering temperature is below 200 °C, while ZnO powder is obtained as sintering temperature increases from 200 to 800 °C. All ZnO and ZnO2 prepared by this method are with crystal structure and high purity. Our fabrication process has low energy consumption and it brings no environment pollution. This simple and green approach is considered of great potential applications in industry.
