Due to the large size of the La 3+ ion, La 2 O 3 adopts a hexagonal 7-coordinate structure that changes to the 6-coordinate structure of scandium oxide (Sc 2 O 3 ) and yttrium oxide (Y 2 O 3 ) at high temperature.
Element substitution for the calcium cation often includes certain rare earth elements (REE), such as yttrium and cerium.
An acronym for erbium yttrium aluminum garnet, this type of device gets its name from the crystal the light passes through in order to focus the energy for the desired effects.
For long distance fibre communication, typically at 1310 nm or 1550 nm, yttrium iron garnet crystals are used (YIG).
However, this position has sometimes been disputed, on the grounds that yttrium and to a lesser extent scandium are closer in their chemical properties to lutetium than lanthanum.
It was soon found that replacing the lanthanum with yttrium (i.
