Preparation of Porous Silicon by Magnesiothermic Reduction from Serpentine

Abstract:

In order to obtain the porous silicon, amorphous silica was prepared from serpentine by leaching experiment The XRF results shows that the leach residues almost compose of amorphous silica, the content is 92.37%, via magnesiothermic reduction, The XRD results shows the amorphous silica was reduced to porous crystal silicon successfully and The SEM results shows they have similar morphology. One of the most important properties of porous silicon was characterized by PL and with an excitation at 365 nm. an emission centered in the blue region.
