Anwendung

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

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.[1],· 
•  The synthesis of Mg-Zr hydrides by treating with MgH₂ for hydrogen storage.[2]       
• The preparation of layer structured β-zirconium nitride chloride (ZrNCl) by reacting with NH₄Cl.[3]

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.[4][5][2]
