It is very well presented and included a few things that were new to me:
use in ceramics
The addition of about 20% scandium carbide to titanium carbide
results in a doubling of the hardness of the mixed Ti -
Sc carbide, to about 50 GPa, second only to diamonds in hardness.
use in electronics
Scandium is used in the preparation of the laser material Gd3Sc2Ga3O12, gadolinium scandium allium garnet(GSGG).
This garnet when doped with both Cr and Nd ions is said to be 3
1/2 times as efficient as the widely used Nd doped yttrium aluminum garnet laser. Ferrites and garnets containing scandium are used primarily in switches in computers. These magnetically
controlled switches work by undulating light passing through the garnet and microwave equipment.
I'll also have to look into both yttrium and also this Ashurst company mentioned in the paper. They seem to have failed to supply the scandium market. They also had external problems and lacked the markets that now exist today.
Maybe they sell lacrosse sticks?
