“…[26][27][28] Low reaction temperatures, short reaction times, a higher amount of magnesium, as well as an experimental set-up with short distances of the silica to the Mg source in principle favor the formation of magnesium silicide during the magnesiothermic reduction. 24,27 It is, however, not possible to create freestanding 3D interconnected networks of phase pure Mg 2 Si crystallites following this procedure even with optimized reaction conditions.…”

“…Therefore worldwide efforts are being directed to develop a low-cost, high-volume and commercially feasible process for production of high purity silicon to be used in solar cells for photovoltaic power generation [269][270][271].One such process involves reduction of rice husk ash to produce silicon.Several approaches have been developed to produce silicon from RHs. Among the various methods, reduction of amorphous silica by metallic metals has been discussed extensivelly.The metallic elements Mg, Ca, Al and Ti can reduce SiO 2 at comparatively lower temperature and forms mixtures of condensed phase products.…”

“…Nevertheless, the high vapor pressure of Ca makes the growth of a continuous film layer by deposition from the gas phase [12][13][14][15][16][17] difficult. Ca atoms are easily evaporated from the Si substrate, which prevents the formation of Ca-silicide by interdiffusion with the Si substrate.…”
