Lithium

Lithium is a semi-rare white alkali metal element that has specialized uses. It has no natural ore found on the overworld or nether. Don't let it touch water.

Obtention
Primarily by shredding schist rock.

Nether quartz ore gives small amounts when centrifuged.

It can sometimes be acquired via meteorites' meteor ore and rarer naturally occurring schist ore.

It can be found in trace amounts when you centrifuge most crystals.

Uses
Its dust form is used with Cobalt to make Lithium-Ion batteries.

It is used in thermonuclear warheads to create Tritium on the spot and initiate the secondary stage fusion-reaction.

When put in rods and bred, it becomes Tritium for use in Fusion Reactors or the Custom Nuke.

It itself can be used in the custom nuke. It contributes 20 to the hydrogen/thermonuclear stage.

Trivia

 * Instead of having an ingot form, it has a "cube" form.
 * Explodes violently when exposed to water.
 * Releases smoke particles when exposed to rain, like lava.
