Definition: norium
norium
\no"ri*um\, n. [NL.] (Chem.)
A supposed metal alleged to have been discovered in 1845 by
the Swedish chemist Swanberg in zircon. After many
unsuccessful attempts to verify this new element, the element
named
Hafnium (atomic number 72) was discoverd in 1923 by
D. Coster and G. von Hevesey in the zirconium-containing
mineral zircon. Hafnium, present at 1 to 5% in many
zirconium-bearing minerals, but difficult to separate from
zirconium, is probably the element that gave rise to the
properties attributed to the hypothetical norium.
[1913 Webster +PJC]
