The direct synthesis methods such as Polymeric Precursor Method can be used as direct route for the synthesis of ceramic-metal composites with high dispersion of metallic nanoparticles. The control of the polymer decomposition in order to avoid the organic matter combustion permits the pyrolysis occurrence, which originates the metallic phase embedded in the ceramic matrix. In this work, a nickel-silica nanocomposite in additional amorphous carbon interphase was successfully obtained through the Polymeric Precursor Method. It was observed by Transmission Electronic Microscopy that metallic nickel nanoparticles nucleate with sizes from 10 to 50 nm inside the mesopore matrix composite. The analysis of Nitrogen Adsorption-Desorption Isotherms for samples pyrolysed at several times showed the existence of two sizes of mesopores, one with diameter of 3.8 nm, associated to the silica-carbon matrix and other above 10 nm, associated to the meso and macropores containing nickel nanoparticles.
