Liquid Uranium

Liquid Uranium is the molten state of Uranium Ore, and it is one of the most useful high-temperature liquids for industrial cooling and heat transfer in Oxygen Not Included. It can remain liquid across an exceptionally wide temperature range, from 132.85°C to 4131.85°C, which makes it especially valuable in builds that need to move heat through very hot environments without the coolant solidifying or boiling away.

One of the biggest advantages of Liquid Uranium is that it is relatively easy to produce compared with other extreme-temperature fluids. Common methods include heating Uranium Ore until it melts, using Uranium Ore to make a Manual Airlock or Mechanized Airlock and placing it against a heat source, running a Kiln made from Uranium Ore in a vacuum until it reaches the melting point, or using a Uranium Centrifuge to obtain liquid output that can be routed directly into a Liquid Pipe and then into a Metal Refinery.

Its broad liquid range makes it well suited to heat exchanger loops and other thermal systems that need a coolant able to survive severe temperature swings. In practice, the limiting factor is often not the liquid itself but the plumbing around it: after repeated heating, Liquid Uranium can become hotter than the melting point of Obsidian or even tungsten, and may eventually exceed the melting point of Insulite as well. For that reason, ordinary pipe materials are often unsuitable in extreme builds, and the pipe type and material become a major design concern.

Liquid Uranium also has a relatively high specific heat capacity. Compared with other molten metals, and at a level comparable to Crude Oil, it can absorb and transport more thermal energy per degree of temperature change. This makes it more stable than many other superhot liquids when used for temperature control, especially in systems operating above one thousand degrees Celsius.

• It is one of the best coolant options for a Metal Refinery in high-temperature industry.
• Its very wide liquid range lets it stay usable in places where many other coolants would fail.
• It is easiest to work with when the surrounding piping and structures can tolerate extreme heat.
• Because it can eventually exceed the limits of common construction materials, long-term use usually requires careful material planning for Liquid Pipe routes.
