Hydrothermal Reaction Sintering of Oxides

  • Shigeyuki Sōmiya

Abstract

Metal powders or chips were reacted with high temperature and high pressure solution to form oxides under certain hydrothermal conditions.
$$ Me + X{H_2}O \to Me{O_X} + X{H_2} $$
(1)
Well sintered oxide body was obtained at 1000°C for 3 to 15 h under high pressure of 100 MPa. One of the most characteristics of the hydrothermal reaction sintered body was fine grains as low as 5 µm even starting materials were over 10 to 5 µm.
