Phosphoric Acid (H3PO4)

Guide by: humanoferth

Phosphoric Acid is available as early as LV but is only really used in the production of PEDOT:PSS in UEV, the production of Polonium Flux, and the production of Sterilized growth medium in ZPM.

Making Phosphoric Acid

Phosphoric acid is made in the Large / regular Chemical Reactor. The only real recipe you'll need to use is the LCR skip that uses Phosphorous, Oxygen, and water on circuit 24:

Other recipes for Phosphoric Acid include:

  • Phosphorous Pentoxide and water in chemical reactor (available before the LCR, uses less energy overall).
  • Apatite, Sulfuric acid, and water in a chemical reactor (would not recommend, has a low yield and Apatite has better uses).
  • As a byproduct in Estalt production.
