Calcium Oxide

Origin

Korea

Calcium Oxide
High quality Calcium Oxide (or Premium Calcium Oxide) which has low in impurities and possessing a high degree of purity (98 to 99 percent) is obtained through the L.P.G Gas calcination (or High quality Calcium Oxide which containing generally 98 to 99 percent calcium oxide produced by L.P.G. Gas Furnace) and it is used in the production of film and rubber to prevent bubble, and it is also used as raw material in many other manufactures, including sealants, special steel for electricity generating and fiber glass. It contributed the import transfer realization of the domestic demand.

Metallurgy
Steel Manufacture and Steel Products Manufacture.
It is available in three forms.

• containing usually 96 percent calcium oxide.
  
• containing usually 90 percent calcium oxide.
  
• containing usually 85 percent calcium oxide.

Chemicals

1. Calcium Carbide is obtained through the controlled calcination (heated up to 1,800°C) of calcium oxide and carbon materials by Electric Furnace,
   
2. Calcium Carbide is obtained through the Electric Furnace with quicklime and carbon materials heated up to 1,800°C,
   
3. Calcium Carbide produced in Electric Furnace by quicklime and carbon materials heated up to 1,800°C,

it is obtained through refrigeration-lithification, crushing and grinding of calcium carbide. In addition, it is used as subsidiary materials for chemical manufactures specially ECH material.
