ferrosilico calcium
Also known as CaSi, it is used for deoxygenation and desulfurization in the production of high-grade steels. Calcium and silicon have a strong ability to absorb oxygen, especially calcium, which has this property not only for oxygen but also for nitrogen and sulfur. 90% of this alloy is used in the steel industry. Silicocalcium is used to control the shape, size, malleability, tempering and other characteristics of steel.
