Reactions of a zinc metal powder with high temperature-high pressure water were studied under 100 MPa. All of Zn powders changed into ZnO above 300 degree C within 1 h in a closed system and also rapidly changed during heating upto 400 degree C in an open system. Zinc powder particles were disintegrated during the reaction due to volume increase in oxidation. The crystallite size of ZnO remained almost constant at 200 degree C, but increased with time above 300 degree C. The crystal growth of ZnO was observed in the open system.
