Close though.

So just to clarify, in the coating process silicon monoxide goes into the chamber
and SiO2 in a tetrahedran structure (Quartz) is formed on the mirror surface?
Is that right?

Interesting point - all the phase diagrams I can find for quartz are around geological pressures, not near vacuum. At the temperatures and pressures in a coating chamber I don't think you'd be forming quartz, but presumably someone who actually knows can chime in!
cheers,
