The Iron Oxide Nanocrystalline Manufactured by IGC-PECS Process (特集 ナノ構造制御と新機能発現) The Iron Oxide Nanocrystalline Manufactured by IGC-PECS Process
The iron oxide nanocrystalline were manufactured by a Inert Gas Condensation - Pulse Electric Current Sintering (IGC-PECS) process. The IGC method involves condensation of vapors of metallic or nonmetallic powders with a controlled residence time in a low pressure environment. The particle size was controlled by pressure of inert gas (He). The smallest average size of powders, 8 nm and the largest average size of powders, 28 nm, were used as a starting precursors for PECS. The smallest average grain size of sintered pellets is 33 nm under the condition at 1073 K with applied pressure of 100 MPa.
