Main ferrosilicon, silicon slag, manganese, silicon carbide, Si-Al-Ba-Ca, Si-Mn alloy, silicon barium iron and other metal.

Using SiAlBaCa to make steel water deoxidized can make the steel-making technology simple, improve product quality and reduce productional cost.

To research the method determining Ca, Ba, Al, Cu in silicon-calcium-barium alloy using Y as internal standard by ICP-AES spectrometer.
