Oxium

"Oxium is a rare lighter than air alloy of Orokin origin."

- In-Game Description

Oxium is an uncommon component. Although dropped by the uncommon enemy unit Oxium Osprey with a perfect drop rate, it can only be found in quantities of 1-3 and will only drop if the Osprey is killed before it destroys itself by charging against the player, an ally, or a wall.

Oxium can also be found in the Orokin Void by destroying canisters, as rare loot in Corpus canisters, and by killing Feral Kubrows.

Gathering Tips
''These tips are based on opinion and may not be true. They should be viewed as advice and not solid fact. Keep in mind that factions on nodes change over time with Invasions, so farming locations will change over time.''
 * Playing Corpus Defense, Survival and Mobile Defense missions can yield 15-30 Oxium per run.
 * Baal on Europa yields at least 5 to 10 Oxium per Data Terminal per mission; it's rare to finish a mission on Baal without acquiring at least 20 Oxium total, and often it's much higher.
