Study on Reactivity of Titanium Beryllide with Water Vapor

摘要

Titanium beryllides such as Be_(12)Ti are considered to become promising alternatives of beryllium as the neutron multiplier. Thus, the authors investigated the reactivity of Be_(12)Ti with water vapor. In the experiments, the Be_(12)Ti sample was exposed to a gas containing water vapor of 10000 ppm at the temperature of as high as 1000 ℃. Chaotic breakaway reactions were not observed for the Be_(12)Ti sample, and the amount of hydrogen generated was found to be far smaller in comparison with beryllium. Thus, it can be said that titanium Be_(12)Ti has less reactivity with water vapor, which is a great merit for the neutron multiplier.
