Abstract

Hydrogenation of Nb75Si25 directly in an arc-melting chamber after arc-melting was investigated. A Nb75Si25 ingot absorbs hydrogen rapidly and simultaneously disintegrates into fine hydride powder. After dehydriding at 1073 K for 10.8 ks, fine Nb75Si25 particles with an irregular angular shape are obtained. The collecting efficiency of powder under 100 mesh is 56.1 wt.%.
