| One of the most important applications of silicon is its use as a deoxidizer in molten steel. |
| Aluminum is widely used as a deoxidizer and was the first element used to control austenite grain growth during reheating. |
| In a vacuum furnace, carbon is an excellent deoxidizer, and the deoxidation product, carbon monoxide gas, is continuously removed under vacuum. |
| Titanium is added as a degasser and deoxidizer, but it also increases fluidity. |
| In steels of this type, silicon is added as the deoxidizer followed by the addition of aluminum for grain size control. |
