Argon is used in situations where materials need to be protected from oxygen or other gases. A good example is an incandescent lightbulb, which consists of a metal wire inside a clear glass bulb. An electric current passes through the wire, causing it to get very hot and give off light.
31 gru 2007 · Most argon is used in the production of steel where it is blown through the molten iron, along with oxygen. The argon does the stirring while the oxygen removes carbon as carbon dioxide. Argon is also used to exclude air to prevent oxidation of hot metals, in welding aluminium and in the production of titanium.
