Calcium strontium or barium, the oxide–nitride coating that results in air is stable and lathe machining and other standard metallurgical techniques are suitable for calcium. In the United States and Canada, calcium is instead produced by reducing lime with aluminium at high temperatures. Calcium provides a link between tectonics, climate, and the carbon cycle. In the simplest terms, uplift of mountains exposes calcium-bearing rocks to chemical weathering and releases Ca into surface water. These ions are transported to the ocean where they react with dissolved CO to form limestone (), which in turn settles to the sea floor where it is
Calcium chlorate Calcium chlorate Calcium chlorate is the calcium salt of chloric acid, with the chemical formula Ca(ClO). Like other chlorates, it is a strong oxidizer. Calcium chlorate is produced by passing chlorine gas through a hot suspension of calcium hydroxide in water, producing calcium hypochlorite, which disproportionates when heated with excess chlorine to give calcium chlorate and calcium chloride: This is also the first step of the Liebig process for the manufacture of potassium chlorate. In theory, electrolysis of hot calcium chloride solution will give chlorate, analogous to the process used for the manufacture of sodium chlorate. In practice, electrolysis is
