The Calcium inoculant’s main components are silicon and calcium, and it also contains different amounts of impurities such as iron, aluminum, carbon, sulfur and phosphorus. Iron and steel industry use it as calcium additive, deoxidizer, desulfurizer and denaturant of non-metallic inclusions. Cast iron industry also uses it as inoculant and denaturant. According to the different contents of calcium and silicon, silicon calcium alloy can be divided into different types.

Barium inoculant is alloy with mainly iron, silicon and barium elements. It can promote graphitization, reduce the tendency of white mouth, and improve the morphology and distribution of graphite. These are available in powder form and finds application in steel-making as well as casting industry. Working as powerful deoxidizer, it also supports demands of improving quality of the products.
