You can probably convert it to oxide by heating it but I don't know what temperature would be required.

The stuff is difficult to keep (it reacts with H2O and or CO2 from the air) so it's generally made where it's needed.

for an experiment with the exothermic reaction with water.

 

and yeah i had considered that but wanted to check if there was an easier way first.
