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.
Overview. Argon is a noble gas. The noble gases are the six elements in Group 18 (VIIIA) of the periodic table. The periodic table is a chart that shows how the chemical elements are related to each other. The noble gases are sometimes called inert gases because Group 18 (VIIIA) elements react with very few other elements.
