Chemical Synthesis of Nanophase Materials

Synthesis of Nanosize Yttria-Stabilized Zirconia by a Molecular Decomposition Process

“…Chemical coprecipitation has been studied extensively for the synthesis of nanosize powders (9). Metallic as well as ceramic powders can be made by carefully controlling the chemistry.…”

“…Several processes have been developed and are currently being used for the synthesis of nanosize powders. These processes include gas-phase condensation, mechanical milling (8), thermal crystallization, chemical precipitation (9), sol}gel process, and aerosol spray pyrolysis (10).…”

“…Alkali metal borohydride, MBH 4 where M is an alkali metal, for example, has been used as a reducing agent in aqueous media for the synthesis of metallic powders. It is important to control the pH and the ionic strength in aqueous media to prevent Ostwald ripening [9]. In the synthesis of nanosize iron oxide, for example, it has been shown that the higher the pH and the higher the ionic strength, the smaller is the size of nanosize particles.…”
