Building Unrefined Prometium in EVE Online

What it takes to make Unrefined Prometium, straight from the game's own blueprint data: every material and how many of each. The calculator above prices that list at one region's orders and draws the whole chain as a graph.

What goes into one run of Unrefined Prometium

1 unit per run - this is a reaction
Material	Per run	Can be built too
Oxygen Fuel Block	5	yes - its own chain
Chromium	100	no - buy or mine it
Cadmium	100	no - buy or mine it

Production runs in whole batches. One run of Unrefined Prometium gives 1 unit, so asking for fewer than that still means one full run - the game has no half runs, and rounding down would quietly tell you to buy the missing pieces.
