gadolinite's Usage Examples:

YTTERBIUM (NEO-YTTERBIUM) [[[symbol]], Yb; atomic weight, 172.0 (0 = '6)1, a metallic chemical element belonging to the rare earth group. Mixed with scandium it was discovered by Marignac in gadolinite in 1878 (see Rare Earths).

It is found in the minerals gadolinite, cerite, samarskite and fergusonite, and is usually obtained from cerite.

The rare earth metals are found in the minerals gadolinite, samarskite, fergusonite, euxenite and cerite.

In 1797 Ekeberg showed that gadolinite contained another rare earth, which was given the name yttria.

The first of the rare earth minerals was discovered in 1794 by Gadolin and was named gadolinite from its discoverer.

In 1878 Marignac, having subjected Mosander's erbia, obtained from gadolinite, to a careful examination, announced the presence of a new element, ytterbium; this discovery was confirmed by Nilson, who in the following year discovered another element, scandium, in Marignac's ytterbia.

The first earth of this group to be isolated (although in an impure form) was yttria, obtained by Gadolin in 1194 from the mineral gadolinite, which was named after its discoverer and investigator.

For the preparation of yttrium compounds the best raw material is gadolinite, which, according to Kiinig, consists of 22.61% of silica, 34.64.
