I. Introduction:
CaSi Alloy is a potent deoxidizer and desulfurizer utilized in the production of high grade steels. Although Silicon itself is a powerful deoxidizer, Calcium is by far more powerful. In addition, Calcium Silicon is used to control the shape, size and distribution of oxide and sulfide inclusions improving fluidity, machinability, ductility, and impact properties of the final product.
CaSi alloy is a potent deoxidizer and desulfurizer utilized in the production of high grade steels.  is also utilized in combination with Barium. The Barium increases the density and reduces the vapor pressure of the alloy, thereby improving efficiency. In cast irons it is used mainly by Pipe Shops for the purpose of coating the inside of each mono cast machine.

Iv. Development History
BOZEL General Electrochemistry company, France, produced silicon-calcium alloy in an electric furnace by the electrosilicon-thermo method around 1907, followed by the electrocarburization method.China smelted calcium and silicon at a calcium carbide plant in Taiyuan in the 1950s.In 1964, Beijing ferroalloy factory successfully studied the process of si-Ca alloy smelting by stratified feeding.
