the guy Posted March 13, 2011 Share Posted March 13, 2011 ''For classroom demonstrations, silane can be produced (temporarily) by heating sand with magnesium powder, then pouring the mixture into a 20% dilution in non-aqueous solution of hydrochloric acid. If silane contacts with water it will react violently. The magnesium silicide reacts with the acid to produce silane gas, which combusts on contact with air and produces tiny explosions'' - if this was repeated in a helium atmosphere would the silane be kept?

insane_alien Posted March 13, 2011 Share Posted March 13, 2011 yes it would. however, i find collecting it in an upturned testtube filled with the acid solution to be the better option. either way, it will slowly diminish over time due to oxygen leaking in from pretty much everywhere.
