General description

This product aligns with one or more of the 12 Principles of Green Chemistry Find details here.
Atomic number of base material: 40

Application

Zirconium(II) hydride (ZrH2) can be used as a precursor for:
  •  Reactive hot-pressing synthesis of Zr2SC ceramics by displacement reaction with the mixture of ZrC and ZrS2.,· 
  •  The synthesis of Mg-Zr hydrides by treating with MgH2 for hydrogen storage.       
  • The preparation of layer structured β-zirconium nitride chloride (ZrNCl) by reacting with NH4Cl.

Zirconium(II) hydride (ZrH2) can be used for the preparation of zirconium diboride (ZrB2) by the reactive plasma sintering process. It can be used as a neutron shielding material, which finds potential usage in hydrogen storage.
Reactant for:
  • Reactive hot-pressing synthesis of Zr2SC ceramics
  • Synthesis of Mg-TM hydrides for hydrogen storage
  • Synthesis of nanocrystal ceramic composites by mechanical alloying
  • Measurement of minimum ignition energies of dust clouds
  • The oxidation of metal hydrides with molecular oxygen
