Kalcijum-hidrid je hemijsko neorgansko jedinjenje hemijske formule CaH₂.

Svojstva

Kalijum-hidrid u čistom stanju (koje se ređe viđa) je bezbojna čvrsta supstanca u vidu kristala ili praha. Nerastvoran je u rastvaračima koji se koriste, a sa vodom burno reaguje.^[4]

Osobina	Vrednost
Particioni koeficijent^[5] (ALogP)	0,0
Rastvorljivost^[6] (logS, log(mol/L))	1,7
Polarna površina^[7] (PSA, Å²)	67,0

Dobijanje

Dobija se prevođenjem vodonika preko zagrejanog kalcijuma.^[4]

Značaj

Pod nazivom hidrolit upotrebljava se za dobijanje vodonika:

CaH₂ + 2 H₂O → Ca(OH)₂ + 2 H₂

Dva proizvoda hidrolize mogu se lako razdvojiti destilacijom, filtracijom ili dekantovanjem.^[4]
