Behavior of Triuranium Disilicide in Water Vapor

  • Published:
Steel in Translation Aims and scope

Abstract

Corrosion resistance of U3Si2 in water vapor is insufficient and increases due to fragmentation caused by formation of the hydride phase. In the present work, samples of triuranium disilicide were tested in an autoclave chamber in the water vapor medium from 350 to 600°C in the presence of a zirconium alloy which is an efficient hydrogen absorber. The dependence of the corrosion rate on the temperature was considered. The order of formation of oxide layers was revealed.
