Calcium phosphide - Wikipedia
Calcium phosphide (CP) is the inorganic compound with the formula Ca3P2. It is one of several phosphides of calcium, being described as the salt-like material composed of Ca2+ and P3−. Other, more exotic calcium phosphides have the formula CaP, CaP3, Ca2P2, and Ca5P8. Ca3P2 has the appearance of red-brown crystalline powder or grey lumps

Calcium metal burns at very high temperatures (it can burn through steel), but reacts much slower than sodium with water. Commercial manufacturers will filter the sodium to remove the calcium. 10
The other Jen''s Blog: What happens to alkali metals in …
When an alkali metal reacts with water it produces an alkali hydroxide and hydrogen gas. During this reaction a massive amount of heat is released which cousts with the hydrogen gas causing the coustion of the entire alkali metal.
Metals and Non-Metals - CBSEGuess
When a metal reacts with dilute nitric acid, then hydrogen gas is not evolved. ( Nitric acid is a strong oxidizing agent , so, as soon as H 2 is formed the nitric acid oxidizes it to water.) Very dilute nitric acid reacts with magnesium and manganese metals to evolve hydrogen gas.

Calcium carbonate is unusual in that its solubility increases as the temperature of the water decreases. The increased solubility of calcium carbonate in rainwater saturated with carbon dioxide is the driving force behind the erosion of limestone rocks, leading to the formation over long periods of time of caverns, caves, stalagmites and stalactites.
