Sakuradite

Sakuradite is a rare mineral found only in the Code Geass universe. Described as the "Philosophers Stone", it was first discovered near Stonehenge some time during the Middle Ages. Marco Polo would later journey to Japan and discover large deposits of the mineral. After Sakuradite became valuable as a superconductor, Japan would become a primary exporter of the material, and produces nearly 70% of the world's Sakuradite to this day.

Prior to its invasion and occupation by the Britannian Empire, Japan used its position as the worlds primary exporter of the mineral as a bargaining chip to exploit consumer nations and increase its own revenue. This eventually sparked the Second Pacific war, in which Japan was conquered. One of the largest Sakuradite mines was recently built on Mount Fuji, much to the dismay of Japanese nationalists.

Its name most likely originates from the word sakura, which in Japan is associated with the color pink.

Properties
The true composition of sakuradite is unknown, but usually appears as a bright pink material. It is most likely a type of rocky ore when first mined, due to the fact of both being the Philosopher's Stone by medieval European culture and that it is mined. After being processed, Sakuradite is both extremely unstable and extremely explosive; a single tanker filled with it had enough destructive force to completely destroy an entire fleet of ships belonging to the Japanese Liberation Front when it was detonated. Sakuradite has both superconductive and radioactive properties, and thus, it is both very valuable and necessary in the production of Knightmare Frames. As a high temperature super conductor, it is used in seventh generation Knightmares and above to conserve energy for high energy demand systems such as Blaze Luminous and Float Systems. As a radioative material, it is used to power Knightmare Frames and fuel nuclear bombs.



Uses
Sakuradite has many uses, the most prominent being the power source of the Knightmare Frame mobile weapons as well as the superconductive power grid for custom 7th generation Knightmares and above. Sakuradite is also used to power most all machinery. It can also be used to make small bombs capable of extreme damage by themselves, although the only instance of these bombs is when Lelouch presents one as a last resort for survival while held at gun point, so it is unknown if these are actually manufactured for military use or if that was the only one.

Weakness
The only real weakness to sakuradite is the Gefjun Disturber, a device that shuts down all sakuradite powered machinery in its range of effect. The disturbers were first used to deactivate enemy Knightmare Frames (the first being the Lancelot), although countermeasures have been developed. The Gefjun Disturber significantly affects both the superconductive and radioactive properties of sakuradite.

Hazard
Sakuradite in its rawest form is one of the most dangerous material in the world, in the Code Geass universe it is basically act as nature Explosive even if the ore is about the size of someone palm tapping both of this substance together can generate massive explosion as shown in Code Geass: Shikkoku no Renya.

Trivia

 * Sumeragi Ishin called Sakuradite "the Exploding Rock."
