[Er-Ni-B-C] [Ho-Ni-B-C]
Material Specification for ; [Lu-Ni-B-C] Process: Melt Processed
Notes: "Samples were prepared by arc-melting and annealing. The starting materials were lanthanide metal shavings or sublimed dendrites (99.9 or 99.99% pure). Ni powder (99.99%) and coarse C (99.99%) and B (99.6%) powders. Samples of 0.75 g total weight were pressed into (6.35 mm = 0.25 in) diameter pellets, which were then arc-melted under argon on a standard water-cooled copper hearth three times, with the melted button turned over between melts. ... Annealing the arc-melted buttons (wrapped in tantalum foil, and sealed in evacuated quartz tubes) for 12-36 h at 1050-1100 °C yielded polycrystalline material with less than 2% impurity phase present."
