Abstract—Nanocomposites can be considered as such strategic materials endowed with designed performance properties that reach far beyond those of conventional composites The ceramic matrix nano composites provide greater deal of interest due to their unique and outstanding physical characteristics. In this present research, It is considered to mix the pure Molybdenum (Mo), Silicon (Si) and Carbon (C) powder in different proportions and continuously ball milled at high temperature for 60 h, as a result reduction of particles took place and SiC of 5% and 20% by weight with MoSi2 Ceramic Nanocomposite were obtained. The above compositions were obtained by adjusting the weight of each elements based on molecular weight of each constituent in chemical reaction. In this work, experimental characterisation for these particles was investigated using Raman Spectroscopy, FTIR, SEM, AFM and Particle size analyser. Phase purity and grain size were determined by X-ray Diffraction analysis. Nanoindentation experiments were performed with Berkovich indenter for determining hardness from Force-displacement data
