Did you know that Tungsten was discovered about 236 years ago, but was not actually used in any industry until another 15 years later? Tungsten is a chemical element that is often used in the production of heavy metals and alloy. It also has applications in chemicals, such as being a high-temperature lubricant and as well as a catalyst for hydrodesulfurization. Tungsten is an interesting chemical element in that there are only 1.25 grams of tungsten for every 1,000 kilograms of Earth’s crust. It is also twice as dense as steel.

Here are some more interesting facts about this interesting chemical element!

1. It has a really high melting point

In fact, tungsten has the highest melting point of any metal in pure form. It is used in a lot of electronics for this reason. These items include light bulbs, a cathode-ray tube, and vacuum tube filaments. Tungsten’s high melting point also makes it a prime element to use for aerospace technology, as well as electrical and heating a

Glass melting electrode

Picture a pot of boiling water with a lid covering it. The steam rises to the lid, condenses, and little water droplets form. Now picture a pot of molten metal with a lid covering it. What happens when you heat the pot hot enough? The same process occurs, except the lid, instead of being coated with water gets coated with a layer of evaporated and resolidified metal. When this process is done in a vacuum, the lid will be covered with a smooth coat of resolidified metal. The pot, in this case, is called a crucible, and the lid is the deposition point. If you changed the shape of a crucible to look like a flattened Viking boat and made it smaller, it would be an evaporation boat.

Wait, how do crucibles get hot enough to boil metal?

Different types of metal have different m
