Description

General description

Calcium borohydride may be prepared using several techniques:
• by reacting diborane with calcium hydride/alkoxides
• by ball milling CaCl2 and NaBH4, resulting in an exchange reaction
• by exchange reaction between CaCl2 and NaBH4 in THF
Ca(BH4)2 decomposes partially at 360oC and completely at 500oC.Ca(BH4)2 finds use in fuel cell, a study reports the lowering of hydrogen release temperature and pressure, by using TiCl3 as dopant.

Sigma Life Science is committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.
