Abstract

In 1990, the Oharai facility of Tohoku University began operations of its unit for research on the materials science of actinide elements. By using high vacuum zone melting and solid state electrolysis, uranium metal was refined up to a purity of 99.99 wt.%. The growth of U2PtSi3 and UGe2 single crystals was achieved by the Czochralski pulling method, using a tri-arc furnace. The Bridgman method using capsulation in a tungsten metal cylinder was employed to grow UTe and USb single crystals. Thin plates of UCu5 and UAl2 amorphous alloys were prepared by sputter deposition. These compounds were characterized by measuring the X-ray diffraction, electrical resistivity, magnetic susceptibility and low temperature specific heat.
