Silicon Calcium

Silicon Calcium Alloy is a compound alloy made up of elements silicon, calcium, and iron, is an ideal compound deoxidizer, desulfurization agent. Silicon Calcium can be obtained in lump or powder form. At present calcium alloy can be used instead of aluminum for final deoxidation, is applied to high-quality steel, special steel and special alloys production. Such as rail and low carbon steel, stainless steel, steel and nickel base alloy, titanium alloy and other special alloy, Calcium Silicon Alloys are used as deoxidizer and desulfurizer in the manufacturing of high grade steel. Indeed, Calcium and Silicon both have a strong chemical affinity for oxygen. Especially calcium, have a strong chemical affinity not only for oxygen, but also for sulphur and nitrogen. The steel industry accounts for around 90 % of global CaSi consumption.

Application and Advantages:
1. Improve the heat resistance, wear resistance and oxidation resistance in refractory material and power metallurgy industry
2. Basic raw material that high polymer of organic silicon formatting.
3. Iron base alloy additive, the alloy pharmaceutical of silicon steel, thus improve the steel hardenability.
4. It is used in high-temperature material production in order to manufacture enamels and pottery and in producing ultra-pure silicon wafers.
