Where to Find Oxygen & Dioxite

Learn the best ways to find Oxygen and Dioxite in No Man's Sky. Discover how to scan for Oxygen-rich plants and mine rock deposits on frozen planets for Dioxite.

The primary uses for Oxygen and Dioxite are for charging the Exosuit Life Support system, the Deep Water Depth Protection Unit, and the Abyssal Air Filter. Each of these will help you to survive on planets in general, though the last two specialize in keeping you alive underwater for long periods of time. You can get a lot of Oxygen from just a few flora samples, and the same goes for Dioxite on a frozen planet with numerous rocks.

Other than these recharging capabilities, Oxygen is also used to craft the Aeration Membrane, Airburst Engine, Efficient Water Jets, Biofuel Reactor, Oxygen Recycler, Personal Refiner, Marine Shelter, and some crafted products such as the Antimatter Housing and Unstable Plasma. Dioxite is used in crafting the Cyclotron Ballista, Hi-Slide Suspension, Thermal Buffer, Thermic Layer, Frostwort, and Granite.

How to Find Oxygen and Dioxite in No Man’s Sky

Scan for Oxygen-rich plants

The main source of Oxygen on any planet is from Oxygen-rich flora. These can be found by scanning the local environment by pressing [Scan button] on your keyboard. They will have the O2 Oxygen chemical element symbol associated with them in a bright red icon, and the plants themselves are always bright red, so they’re easy to spot and distinguish from other flora in the landscape. You can also find Oxygen as a secondary element in some flora, so be sure to check whatever flora you encounter with the Analysis Visor to see which elements are present.

Mine Rock Deposits on Frozen Planets for Dioxite

If you want to find Dioxite reliably, you’ll need to visit a frozen planet. You shouldn’t have to warp to many systems before you encounter one, and you can use the scanner on your starship to inspect a planet to check its type, and whether Dioxite is mentioned in its primary materials list. Once you’re on a frozen planet, all you need to do is inspect any rocks that you encounter with the Analysis Visor. This will tell you whether Dioxite is present as a secondary element within the rock. If it is, you can mine the rock and extract the Dioxite from it.

Other Sources of Oxygen and Dioxite

Aside from finding Oxygen from the scannable flora present on almost every planet, you can also extract it from the atmosphere using an Oxygen Harvester or Atmosphere Harvester, both of which are base construction modules which can be acquired from the Construction Research Station on board the Space Anomaly if you don’t already have them. You can also use a Gas Extractor to harvest Oxygen or Dioxite on a more industrial scale, but you’ll need to find an appropriate hotspot using the Survey Device Upgrade for the Analysis Visor. You can also refine Oxygen and Dioxite from various materials.
