|Geneva—Jean Charles Galissard de Marignac elements|
- Jean Charles Galissard de Marignac
- found a new spectroscopic line in gadolinite.
- He had suspected that something yet undiscovered
- was muddying tests of Mosander’s derivation from cerite.
- De Marignac separated the new oxide from cerite
- and named it for gadolinite after Johan Gadolin.
Atomic number 64
- Gadolinium make good shielding for nuclear reactors.
- Small amounts of gadolinium improves the workability of other metals.
- Gadopentetic acid is given intraveniously as an MRI contrast agent.
- Green gadolinium phosphors were used for color television tubes.
- The gadolinium yttrium garnet has various uses in optical equipment.
- The gadolinium gallium garnet is an imitation diamond.
- Gadolinium’s magnetocaloric effect makes magnetic refrigerators work.
- Gadolinium-153 emits gamma rays for testing bone density.
You have no idea
- You have no idea what this stuff does.
- Most people haven’t the vaguest notion.
- If you’ve never seen it before, if
- you’ve never heard about it, if
- you’ve never read about it, then
- why should you even think of it?
- On the other hand, what if this stuff
- were the key to antigravitation? What if
- it let you save 99% of the energy
- of sunlight? What if it made a rechargable
- battery with higher energy density
- than diesel? Well, you just have no idea.
