摘要

Hydrothermal reaction sintering is one of the methods to prepare oxides ceramics. Metals, intermetallic compounds or alloys are sealed in a Pt capsule with water. On heating they react with high pressure high temperature water, and produce metal oxides and hydrogen gas. The known quantities of alloy powders; water-atomized permalloy powder (Fe-47 wt% Ni less than #100, and Fe-36 wt% Ni less than #100) and redistilled water were hermetically sealed with an electric arc in a platinum capsule 2. 7 mm inside diameter, 0. 15 mm thick and 35 mm long. This capsule was treated at 100 MPa, 800 degree -1000 degree C, for 10-240 min in a high pressure high temperature apparatus using Ar gas as pressurizing medium. The produced sintered ceramics were examined by X-ray diffraction, optical and scanning electron microscopy, and energy dispersive spectroscopy (EDS).
