Silicon calcium is not called calcium silica, containing calcium 22 to 35%, silicon 60 to 65%. YB 525-65 specifies no less than 31%, 28% and 24% calcium content. It is mainly used as a incubator for cast iron. Silicon calcium alloy has a strong reduction ability and is also used as an oxygen at high-quality steel.
