RHENIUM DIOXIDE
DESCRIPTION
Rhenium Dioxide is a reddish brown powder represented by the formula ReO₂. It is insoluble in water and aqueous alkalis, but it is readily attacked by oxidizing acids and alkaline hydrogen peroxide solutions to give the perrhenate ion.
The specific gravity is 11.4 gm/cc. Rhenium Dioxide sublimes at an estimated temperature of 1363° C (2485° F).
