ABSTRACT

A direct synthesis method is introduced to prepare nano-porous silicon-nickel nanocomposite (nPS/Ni) powder for thermal isolation applications. In this paper, we study the thermal stability of nanocomposites consisting of nanoparticles metal incorporated into the pores of a porous silicon by a very simple method. The nickel element is chemically deposited whereas the nanoparticles are precipitated on the pore surfaces. The (nPS) and (nPS/Ni) nano-materials are thermally measured under nitrogen at temperatures of 40℃ - 1000℃, noticeable, demonstrating better thermal stability of (nPS/Ni) until 900℃ than in the case of (nPS) at 600℃. Then, the improving of the thermal stability of the nPS powder is facilitated using it in many applications of the thermal insulation process.
