Schrabidium

Schrabidium is a fictional material added to HBM's Nuclear Tech Mod, and is quite possibly the most well-known material in the mod. It is extremely radioactive with each ingot providing 15 RAD/s. It has a multitude of uses including high-tier reactor fuel, next-gen nuclear weapons, producing truly exotic materials, and even as a core part of highly advanced bullets and batteries.

Unlike most other radioactive materials, Schrabidium only has 1 useful isotope, Sa326. The other slightly heavier isotope, Sa327 or Solinium, is much less useful, except in the production of Euphemium in a Breeding Reactor and one unusual bomb. It can also be used as a fuel for Breeding Reactors or Nuclear Furnaces, although this is rather inadvisable due to the high production cost of Solinium.

Production
For more information, see Guide: Schrabidium Creation

In the mod's lore, it was discovered after a nuclear detonation revealed a vein of uranium ore right on the edge of destruction, and through the apparent intense heat, radiation, and pressure, it was able to be turned into Schrabidium ore.

The Schrabidium Transmutation Device recreates this process in a controlled manner using extremely high amounts of electrical energy.

A Higgs Boson particle is also capable of transmutating Uranium into Schrabidium at 100% efficiency.

It can also be produced in a particle accelerator, but only in tiny amounts (nuggets) from Ionized Particles, a byproduct of most Fusion reactions.

Uses
Schrabidium is the "easiest" special fictional material to obtain and it has the most uses as well to reflect it. Its incredible density, radioactivity, and instability allow it to be used in armor, weapons (not just the nuclear kind), energy storage, high-tier circuitry, and fuel.

Pure Schrabidium Fuel Pellets are the best source of power for a Watz Power Plant, but a normal reactor needs something more stable. Schrabidium can be partially stabilized by mixing it with Neptunium and Beryllium in fuels. This makes SNB (Schrabidium-Neptunium-Beryllium) fuel, which comes in the forms of high, medium, and low enriched Schrabidium fuel.

It can be used in the Custom Nuke: Schrabidium items contribute to the Schrabidium stage in it:
 * Nuggets: 0.5
 * Ingots: 5
 * Blocks: 50
 * Trisulfide Cells: 7.5

Properties

 * It has a very high atomic number of #126.
 * ~312amu in atomic weight.
 * Gargantuan density of 39,700 kg/m3
 * Appears to be very magnetic.
 * It appears to work well with boosting Tungsten's magnetism to create Magnetized Tungsten, which appears to be quite a temperature resistant material.
 * Emits some kind of high penetrating radiation that causes blindness for as long as the Schrabidium item is held. Only blocked by tier 3 hazmat suits (or equivalent) or higher. Exception is Euphemium armor, which does not block it.

Trivia

 * On the cusp of being unstable, right inside the island of stability.
 * Is actually grey in color, the blue color apparently comes from quick corrosion, probably oxidation.
 * Solinium's color is probably representative of Schrabidium's true color.
 * Is bred from Uranium most of the time.
 * "Likes" Neptunium, Beryllium, and Tungsten (but mostly Neptunium).
 * It is a reference to Sakuradite from Code Geass, but somewhat more realistic and with a German sounding name instead of a Japanese one.
