Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 10049-08-8, Cl3Ru.

We demonstrate a new solid-state synthesis route to prepare calcium borohydride, Ca(BH4)2 by reacting a ball-milled mixture of CaB6 and CaH2 in a molar ratio of 1:2 at 700 bar of H2 pressure and 400-440C. Moreover, doping with catalysts was found to be crucial to enhance reaction kinetics. Thermogravimetric analysis and differential scanning calorimetry revealed a reversible low-temperature to high-temperature endothermic phase transition at 140C and another endothermic phase transition at 350-390C associated with hydrogen release upon formation of CaB6 and CaH2, as was evident from X-ray diffraction analysis. Thus, since Ca(BH4)2 here is shown to be prepared from its anticipated decomposition products, the conclusion is that it has potential to be utilized as a reversible hydrogen storage material. The theoretical reversible capacity was 9.6 wt % hydrogen.
