Si-Ca-Ba is an new and high efficent complex alloy of Ba Series;Can be used as deoxidizer and dusulfurizer, and dephosphorization effect.
in Steel-making industry,for foundry it can be used as Inoculant and metamorphic agent .
Ba can effectively reduce the vapor pressure of Ca,increase the solubility of Ca in the molten steel; 
It is proved that Ba effectively protect Ca in molten steel,reduce the oxidation of Ca, so as to meet the purpose of handling calcium
 in molten steel.
