Silicon

Silicon is a fundamental raw material in Mindustry used across industry, defenses, and unit production. It is produced by the Silicon Arc Furnace and serves as a common construction component for many buildings, a component in certain turret ammunition, an input for Surge Alloy, and a direct or indirect requirement in the manufacture of all units.

Silicon appears in the recipes for a wide range of factories and structures. It is required by vehicle and unit production lines such as Tank Fabricator, Moss Fabricator, Ship Fabricator and their corresponding Refabricators and Assemblers (Tank Refabricator, Moss Refabricator, Ship Refabricator, Prime Refabricator, Tank Assembler, Moss Assembler, Ship Assembler). It is also consumed by specialized production and processing buildings including the Surge Crucible, Electrolyzer, Oxidation Chamber, Cyanogen Synthesizer, Phase Synthesizer, Pyrolysis Generator, Flux Reactor, Neoplasia Reactor and the Chemical Combustion Chamber. Silicon is part of many utility and defensive structures as well: Radar, Build Tower, Regen Projector, Shockwave Tower, Beam Tower, Unit Repair Tower, and various transport and cargo buildings such as Unit Cargo Loader/Unload Point and Duct Unloader. Mining and resource-processing equipment that require silicon include Impact Drill, Eruption Drill, Reinforced Pump and the Advanced Plasma Bore. Silicon is also used in core construction (Core: Bastion, Core: Citadel, Core: Acropolis) and in several high-tier turret and unit chassis blueprints (Breach, Diffuse, Afflict, Lustre, Scathe, Malign and various mass driver and payload devices). Large Deconstructor and other deconstruction or refabrication buildings likewise consume silicon in their recipes.

Beyond in-game usage, silicon corresponds to the real-world element silicon (Si), atomic number 14, commonly utilized in electronics for its semiconductor properties. It should not be confused with silicone, which is an organic polymer. Industrially, silicon is typically obtained by reducing silicon dioxide (for example, sand) with carbon according to the chemical reaction SiO2 + 2C → Si + 2CO; this real-world chemistry loosely mirrors the game’s concept of refining raw materials into usable industrial inputs.

• Prioritize establishing reliable silicon production early to unlock and sustain mid- and late-game factories and advanced turrets; many high-tier structures and units depend on a steady silicon supply.
• Silicon’s ubiquity means bottlenecks in silicon will cascade into slowed unit production, inability to craft Surge Alloy, and stalled defensive upgrades—monitor consumption across refabricators, assemblers, and key reactors.
• Because silicon feeds both construction and ammunition lines, plan logistics so that refineries, storage, and conveyor networks can supply multiple production hubs without starving one important consumer.
