To recreate hydrogen storage materials from literature, a tube furnace will be used to form lithium-magnesium-nitride from pelletized powder precursors, lithium nitride (Li3N) and magnesium nitride (Mg3N2). The quartz tube will be heated to up 900 to 1000K while a carrier gas will flow through the tube and discharge to the fume hood. Rev.1 The procedure described above may be extended to the synthesis of other nitrides using the same procedure. The same furnace may also be employed in the sintering of compounds in an inert atmosphere such as argon or helium. This sintering helps create a homogeneous product.
