This paper describes the development of composites of calcium phosphate and silica, wherein the silica is obtained from rice husk as a natural source. The objective was to develop calcium phosphate composites and silica that meet physical and chemical characteristics for potential applications in bone treatments as synthetic filler and assess their degradation in simulated physiological fluid. Carried out the synthesis of each of the materials and the physicochemical characterization of each composite and formed by means of analysis by X- ray diffraction (XRD) and scanning electron microscopy (SEM), degradation tests were carried out with the material. The composite was developed using metallurgy of powders of calcium phosphate and silica. The results showed that the calcium phosphate composite and silica obtained from rice hush can be used as synthetic bone filling material with the synthetic connotation variant.
