Abstract

Certain properties of clean uranium in vacuum have been investigated. The following values were found: for emissivity below the melting point (λ=0.67μ), 0.51; for thermionic work function, 3.27±0.05 volts, with a Richardson A of about 6; for melting point, 1700±25°C; for average coefficient of linear expansion, 25°C to 1000°C, 4× 105.
