Dear Sir/Madam,
Will the following reaction take place:-
Silica sand + hydrogen --> silicon + steam
SiO2 + 2H2 --> Si + 2H2O
Will it be necessary to heat up the silica sand before passing the hydrogen through it ?
Thank you in anticipation

Yes, the reaction will take place. It requires temperatures well above 1000 C -- possibly up to 1400 C.
