Making silane from calcium silicide


Im looking forward to synthesizing silane from Ca2Si
I realize how dangerous this compound is, and im only going to make a tiny amount, burning it immediately
The process should be analogous to the Mg2Si reaction:
Mg2Si + 4HCl = SiH4 + 2MgCl2
My question is, can I use HNO3, which I have a lot of, or is the hydrochloric acid necessary?

HNO3 might oxidise the silane.
Vinegar would probably do the job.

Silane spontaneously combusts explosively in air doesn't it ?

John paul III's photos after he's done this will be awesome.

Looking forward to seeing those photos.

How are you making the calcium silicide? Or are you buying it someplace?

The higher molecular wight silanes are being investigated for propellants and scram jets... as they are liquid and can combust in nitrogen too...

Not much information can be found about them, which makes me think its been quite for a reason... perhaps it does work very well for military fuel...
