Zinc vs. Zinc Oxide: What's the Difference?
Zinc is a metallic element, while zinc oxide is a chemical compound made of zinc and oxygen.
Zinc is a natural metallic element, known as a transition metal, crucial in many biological processes. On the other hand, zinc oxide is a compound formed when zinc is chemically combined with oxygen.
Zinc is used in its metallic form for various industrial applications, including galvanization. Zinc oxide, however, is widely used in products like sunscreens and ointments due to its protective properties.
In its pure form, zinc is a bluish-silver metal, known for its corrosion-resistant properties. Zinc oxide appears as a white powder and is used for its sun-blocking and skin-protecting abilities.
Zinc is an essential dietary mineral important for immune function and enzyme reactions. Zinc oxide is not ingested for dietary benefits but is used topically for skin protection and care.
In the environment, zinc occurs naturally in ores, while zinc oxide is synthesized for commercial use and is not found naturally.

Zinc oxide helps improve the strength of rubber tires.
A bluish-white, lustrous metallic element that is brittle at room temperature but malleable with heating. It is used to form a wide variety of alloys including brass, bronze, various solders, and nickel silver, in galvanizing iron and other metals, for electric fuses, anodes, meter cases and batteries, and in roofing, gutters, and various household objects. US pennies minted after 1982 consist of a copper-clad zinc core. Atomic number 30; atomic weight 65.38; melting point 419.53°C; boiling point 907°C; specific gravity 7.134 (at 25°C); valence 2. See Periodic Table.
To coat or treat with zinc; galvanize.
What is zinc oxide?
