What is Calcium Metal?
Calcium is a bright silvery-white metal. Under norm alatmospheric
conditions, however, freshly exposed surfaces of calcium rapidly become covered with an oxide layer. The metal is extremely soft and ductile, having a hardness between that of sodium and aluminum. Calcium is very reactive and reacts vigorously with water, liberating hydrogen and forming calcium hydroxide, Ca(OH)2 . Calcium does not readily oxidize in dry air at room temperature, but is quickly oxidized in moist or dry oxygen at about 300o C.

Types of Calcium Metal
Calcium Metal Production Processes
Calcium metal is produced by the aluminothermic method involving the high temperature vacuum reduction of calcium oxide. The raw materials for this process are limestone and aluminum. In this process, aluminum metal acts as the reducing agent。

Calcium Metal Price Forecast
The demand for calcium products is average, and there is no direct benefit to the market. The price of external magnesium ingots also shows a trend of rising first and then falling, and the trend is unstable, which makes calcium metal factories dare not adjust the price rashly. It is expected that the short-term calcium metal market will remain stalemate and stable.
