Most Common Uses of Zinc
1. Galvanizing
Zinc is widely used for galvanizing steel and iron to protect them from corrosion. The process involves coating the metal surface with a layer of zinc, which acts as a sacrificial anode.
This means that the zinc layer corrodes instead of the underlying metal, extending the lifespan of the coated object. Galvanized steel is commonly used in construction, automotive, and electrical industries.
2. Alloying
Zinc is often used as an alloying element in the production of various metals. It is commonly added to copper to create brass, a versatile alloy with excellent corrosion resistance and malleability.
Zinc is also alloyed with aluminum to form zinc-aluminum alloys, which are lightweight and have high strength. These alloys find applications in the aerospace industry, automotive parts, and electrical connectors.
3. Dietary Supplement
Zinc is an essential mineral for human health and is often taken as a dietary supplement. It plays a crucial role in various bodily functions, including immune system support, wound healing, and DNA synthesis.
Zinc supplements are commonly used to prevent and treat zinc deficiency, which can lead to impaired growth, weakened immune system, and other health issues.

Chemistry of Zinc
Discovery
Zinc, a chemical element with the symbol Zn and atomic number 30, has a rich history that dates back thousands of years.
The discovery of zinc can be traced back to ancient times, with evidence of its use found in archaeological sites in ancient Egypt and Rome. However, it was not until the 16th century that zinc was recognized as a distinct metal.
The German alchemist Andreas Libavius is credited with first isolating zinc in its pure form in the late 16th century.
History
Zinc has been used by humans for various purposes throughout history. The ancient Egyptians used zinc compounds for medicinal purposes, while the Romans used zinc to make brass, a copper-zinc alloy.
In the 18th century, zinc became more widely recognized as a valuable metal. The process of smelting zinc from its ores was developed, leading to increased production and use of zinc in various industries.
Basic Chemistry
Zinc is a bluish-white metal that is relatively soft and malleable. It has a melting point of 419.5 degrees Celsius and a boiling point of 907 degrees Celsius.
In its pure form, zinc is resistant to corrosion, making it a popular choice for galvanizing steel to protect it from rust. Zinc is also an essential trace element for living organisms, playing a crucial role in various biological processes.
Zinc is commonly found in the Earth’s crust, usually in the form of zinc sulfide or zinc oxide ores. The most common ore of zinc is sphalerite, which is a zinc sulfide mineral.
It can be extracted from its ores through a process called roasting, where the ore is heated in the presence of oxygen to convert the zinc sulfide into zinc oxide. The zinc oxide is then reduced to metallic zinc using carbon or carbon monoxide.
Zinc has a wide range of applications due to its unique properties. It is used in the production of alloys, such as brass and bronze, which are widely used in various industries.
It is also used as a coating for steel to protect it from corrosion, as well as in the production of batteries, fertilizers, and pigments. Additionally, zinc compounds are used in various pharmaceuticals and dietary supplements.
Interesting Physical Properties of Zinc
