Description
New techniques for the drawing of rhodium, which is exceptionally hard and difficult to fabricate, are described. Pure rhodium sponge was formed, then melted in a high-frequency induction furnace. Wire of a fibrous nature was produced through a series of swaging operations at gradually decreasing temperatures (beginning at 800~C). The melting point, hardness, thermal expansion, density, and electrical resistivity of the forged rhodium are reported.
