The nanocomposite often improves not only the mechanical properties such as failure strength, fracture toughness, fatigue and ware resistances, etc. of structural ceramics but also the electrical, magnetic, and optical properties of functional ceramics. In this study, we propose a novel processing technique to fabricate nanocomposite. The composite powders, i.e., nano-sized additive particles coated on the surface of matrix particles has successfully fabricated in this study. It was concluded that the proposed electrostatic adsorption assembly technique is an efficient tool for designing of microstructural controlled nanocomposites.
