Ta'rif
Taʼrifi
Excellent oxidation resistance calcium silicon.One of the reasons for the excellent oxidation resistance of Si-Ca alloy is that it can undergo oxidation reaction at high temperature, forming a dense oxide film, which slows down or prevents further oxidation reaction. When the silicon calcium alloy is exposed to oxygen at high temperatures, the silicon on the surface of the silicon calcium alloy will react with oxygen to form a dense silica film, which can effectively isolate the contact between oxygen and the alloy, thereby preventing the alloy from being further oxidized. In addition, the calcium element in the silicon calcium alloy can form a calcium oxide film with oxygen, which has high stability and can effectively improve the oxidation resistance of the alloy.
