Application and Uses:
- Zinc oxide along with stearic acid is used in the vulcanization of rubber.
- ZnO additive also protect rubber from fungi (see medical applications) and UV light.
- Zinc oxide as a mixture with about 0.5% iron(III) oxide (Fe2O3) is called calamine and is used in calamine lotion.
- Ceramic industry consumes a significant amount of zinc oxide, in particular in ceramic glaze and frit compositions.
- Zinc oxide can be used in ointments, creams, and lotions to protect against sunburn and other damage to the skin caused by ultraviolet light.
- Zinc oxide is a constituent of cigarette filters.
- Zinc oxide is added to many food products, including breakfast cereals, as a source of zinc, a necessary nutrient.
- Zinc white is used as a pigment in paints and is more opaque than lithopone, but less opaque than titanium dioxide.
- It is also used in coatings for paper.
- Micronized and nano-scale zinc oxide and titanium dioxide provide strong protection against UVA ultraviolet radiation, and are used in suntan lotion.
- Paints containing zinc oxide powder have long been utilized as anticorrosive coatings for metals. They are especially effective for galvanized iron.
- Zinc oxide depleted in Zn (the zinc isotope with atomic mass 64) is used in corrosion prevention in nuclear pressurized water reactors.
- Zinc oxide (ZnO) is used as a pretreatment step to remove hydrogen sulfide (H2S) from natural gas.
