Abstract

original image

The use of magnesiothermic reduction and CVD to obtain Si spheres is reported. The porous structures of the Si spheres after the former process and the infilling of their pores after the latter one are observed. The optical properties of opals formed with these spheres are used to assess the power of the method and the quality of the final product.
