Rhenium characteristics
Rhenium acid
Rhenium is a silvery white metal. The hexagonal lattice with a = 27546
a, C = 44480 a.
Rhenium characteristics
Rhenium characteristics
The melting temperature is only slightly lower than the melting point of
tungsten.
Pure metals have high plasticity. The rhenium stack produced by the
cermet process similar to tungsten can be forged when heated to 800 ℃.
It is stable in air at ordinary rhenium temperature. When the metal is
heated to 1000 ℃, obvious oxidation can be observed. Powdered rhenium is
easy to burn in air and produce volatile Re2O7 oxide. Rhenium does not
produce chemical compounds with nitrogen and hydrogen. The latter is
buried in powdered metal. Halide reacts with grey rhenium when heated.
Rhenium does not corrode in hydrochloric acid and molten acid. Sulfuric
acid has little effect on metals when heated to 100 ℃. Rhenium acid can
be dissolved in rhenium nitrate.
The standard rhenium potential is 0.6 W.
