Introduction To Tungsten
Tungsten is a fascinating metal known for its high density. It is widely used in various industries. But what makes it so unique? Let’s dive into the properties and history of this incredible element.
What Is Tungsten?
Tungsten, also known as wolfram, is a chemical element with the symbol W. It has an atomic number of 74. Tungsten is remarkable for its high melting point. It melts at 3422°C (6192°F), which is the highest of all metals.
This metal is also very dense. Its density is approximately 19.25 grams per cubic centimeter. This is almost as dense as gold. Tungsten is hard and resistant to wear and corrosion. These properties make it valuable in many applications.
Historical Background
Tungsten’s history dates back to the 18th century. Two Spanish chemists, Juan José and Fausto Elhuyar, discovered it in 1783. They isolated tungsten from the mineral wolframite.
The name “tungsten” comes from Swedish words meaning “heavy stone.” The element’s symbol, W, comes from its German name, “wolfram.” The discovery of tungsten opened up new possibilities in metallurgy and industry.
Tungsten quickly became essential for making strong, durable tools. Its high melting point made it ideal for high-temperature applications. Over the years, tungsten has remained a critical material in many fields.
