Carbon Nanotube

Carbon nanotubes are an ultra-high-strength synthetic material used in some of the game’s most demanding production chains. They are made in a Chemical Plant, with the standard recipe using graphene and titanium ingots, while an advanced recipe allows direct production from Spiniform stalagmite crystals. Because the normal route relies on graphene, its supply is often tied to how efficiently crude oil is processed into graphene, making carbon nanotubes a material whose production needs careful planning if large quantities are required.

They are a key ingredient for Frame Material and Particle Broadband, and they are also used in higher-end manufacturing, including Proliferator Mk.III. As a result, they sit at the center of multiple late-game logistics chains rather than serving only one specialized purpose. The Spiniform stalagmite crystal recipe is especially valuable because it bypasses the graphene bottleneck, and it is also the only other use for Spiniform stalagmite crystals besides carbon nanotube production, so those crystals are effectively reserved for this one material.

A few practical points are worth keeping in mind:

• Carbon nanotubes can be found in small amounts by harvesting certain plants, especially larger trees on Mariterra, Prairiea, Crimsonis, and Tropicana planets.
• These natural drops are far too limited for serious production; clearing an entire planet usually yields only enough for one or two items.
• The normal graphite-to-graphene route can become wasteful if production is not balanced carefully, especially when early oil processing is still constrained.
• Once access to Fire Ice or Spiniform stalagmite crystals is available, carbon nanotube production becomes much easier to scale.
• The advanced crystal-based recipe increased from 2 to 6 Spiniform stalagmite crystals in version 0.9.26.12891, which reflects its role as a higher-cost but convenient alternative.

In practice, carbon nanotubes are best treated as a strategic intermediate rather than a standalone commodity. Their demand rises sharply once Frame material, Particle broadband, and other advanced components enter the supply chain, so setting up stable production early can prevent bottlenecks later.
