Application

Calcium hydride (CaH2) is a metal hydride that can be used for a variety of greener applications such as:
  • fabrication of hydrogen storage systems for fuel cell applications
  • synthesis of porous aromatic frameworks (PAFs) for adsorption of organic pollutants
  • formation of high temperature superconductors

Calcium hydride is widely used as a drying agent for organic solvents.1 It has been used to dry ε-caprolactone,benzene and toluene.
