Zinc oxide is an inorganic compound that is a white powder substance that is insoluble in water and alcohol, but can be dissolved in most acids (including hydrochloric acid). Zinc oxide is known to react strongly with aluminum and magnesium powders. Another interesting property of this inorganic compound is its ability to absorb ultraviolet light. In addition, zinc oxide has adhesion, luminescence, high thermal conductivity and antibacterial properties. In the modern world, zinc oxide has a variety of uses，it is known to be widely used in the industrial, pharmaceutical, and cosmetic industries.
1. Physical properties
Appearance and properties: white powder or hexagonal crystal. It is odorless, tasteless and sandless. It turns yellow when heated, and turns white again after cooling, and sublimates when heated to 1800 ℃. The covering power is half of that of titanium dioxide and zinc sulfide. The coloring power is twice that of basic lead carbonate.
Solubility: soluble in acid, concentrated hydroxide alkali, ammonia water and ammonium salt solution, insoluble in water and ethanol.
2. Chemical properties
Zinc oxide is a famous white pigment, commonly known as zinc white. Its advantage is that it will not be black when encountering H2S gas, because ZnS is also white. During heating, ZnO gradually changes from white and light yellow to lemon yellow. When it cools down, the yellow will fade away. Use this feature to mix it into paint or thermometer to make color change paint or color change thermometer. Because ZnO has astringency and certain bactericidal ability, it is often mixed into ointment for use in medicine, and ZnO can also be used as a catalyst.
1. Zinc oxide has antibacterial properties and is widely used in the treatment of various skin conditions. It is used as a topical ointment to help relieve skin irritation, diaper rash, minor burns, dry and chapped skin, and other problems.
2. Because of its medicinal properties, zinc oxide is also added to baby powder, anti-dandruff shampoos, antibacterial ointments, and surgical tape.
3. In addition to iron oxide, zinc oxide is also used in the production of furnace glycolate lotion.
4.Zinc oxide is mixed with eugenol to form zinc oxide eugenol, a restorative and filling agent in dentistry.
5. Zinc oxide's ability to treat itching and skin irritation has made it an important ingredient in many rectal suppositories used to relieve allergies and discomfort caused by hemorrhoids.
6. It is also a source of mineral nutrition and zinc is biochemically essential for many of the body's biochemical needs. Zinc oxide is also added to foods or vitamin supplements as a source of zinc. Zinc contributes to a healthy immune system.
