Ferro Silicon Zirconium is an alloy composed of iron, silicon, and zirconium. It is commonly utilized as an additive in steelmaking to enhance the strength and ductility of the resulting steel. The addition of zirconium helps refine the grain structure of the steel, thereby improving its mechanical properties.

Ferro Silicon Zirconium is typically produced by smelting a mixture of ferrosilicon, zircon sand, and other materials in an electric furnace. The resulting alloy is then crushed into various sizes and used as an additive in steelmaking.
