However, safety, high quality and volume density are barriers for the developement of hydrogen storage materials[1].
LiH (Alfa Aesar,99.4%), LiAlH4 (Alfa Aesar,95%), MgH2 (Alfa Aesar,98%) and AlCl3 (Alfa Aesar,99.985%) were used as starting materials.

Both materials were sintered at 1250 °C.
As compared to pressureless sintering, hot-pressing and ultra fine WC-materials resulted in denser materials and consequently hardner specimens.
