You're shivering. Your hazard protection is screaming at you because the temperature just plummeted to -100 degrees Celsius, and you realize you're out of fuel. This is the classic "frozen planet" panic. If you’ve spent any time at all in No Man's Sky, you know that Dioxite is basically the lifeblood of cold-world survival. It’s that blue-tinted isotope that keeps your life support humming and your base powered when the frost starts creeping across your visor. But honestly, most people spend way too much time wandering around aimlessly looking for it when there are much faster ways to fill your inventory.
Where Dioxite Actually Hides
You won't find this stuff everywhere. It's a localized resource. Specifically, you need to be looking for frozen biomes. When you're up in your ship scanning planets, look for descriptors like "Frozen," "Ice," "Glacial," or "Sub-zero." If the planet has those tags, there is a high statistical probability that Dioxite is the secondary or tertiary resource listed in the planetary scan.
Once you land, pull out your Analysis Visor. You aren't just looking for random rocks. You’re looking for blue crystals or specific mineral deposits. Sometimes it’s tucked away as a secondary element inside common silicate rocks. You’ll be mining for Ferrite Dust and—surprise—a little bit of Dioxite pops out. It's a nice bonus, but it's not efficient for high-level crafting or long-term survival.
The Large Deposit Strategy
Look for the "Resource Deposit" icons in your visor. If you see one labeled Dioxite, that’s your jackpot. Use your Terrain Manipulator. Don't just blast it on the highest setting, though. If you set your Terrain Manipulator to the smallest beam size, you actually extract more total resources from the same node. It takes longer. It's tedious. But if you’re low on fuel, it’s the difference between one stack and three.
Refining Is the Real Pro Move
Mining is for beginners. If you want to actually get rich in No Man's Sky—or at least never worry about freezing to death again—you need to use a Refiner. There are recipes that feel almost like cheating because of how much Dioxite they pump out for very little effort.

Basically, you can "multiply" your resources.
If you have some Condensed Carbon and some Sodium Nitrate, throw them into a Medium or Large Refiner. This produces Dioxite at a decent rate. But if you want the real "infinite" loop, you use the Frost Crystal method. Frost Crystals grow naturally on the same frozen planets where Dioxite lives. If you mix 2 units of Frost Crystal with 1 unit of Salt, you get Dioxite.
Wait, it gets better.
You can actually combine Dioxite with Oxygen to create more Frost Crystals. Then you take those crystals, mix them with more Salt, and create more Dioxite. It’s a closed-loop system that keeps your base running forever. Most players forget that Oxygen is the "catalyst" for almost everything in this game. If you have an Oxygen harvester, you basically have an infinite supply of whatever mineral you want, provided you have the right recipe.

Why You Actually Need It (Beyond Survival)
It’s not just about staying warm. Dioxite is a core component in several high-tier crafting recipes. If you're trying to build a complex base or upgrade your starship, you're going to hit a wall without it.
- Grantine: This is a trade commodity used for high-level crafting. You need Dioxite and Ionised Cobalt to make it.
- Aromatic Processing: If you’re into the cooking side of No Man's Sky (which, let's be real, most people ignore until they realize how many nanites it’s worth), Dioxite is used in some niche refining processes.
- Environmental Protection Upgrades: This is the big one. Your Cold Protection modules need Dioxite to recharge. Using it is way more efficient than using Life Support Gels or raw Carbon.
Buying Your Way Out of the Grind
Let's say you're lazy. Or maybe you're just rich in Units and don't feel like freezing your toes off on a Hoth-lookalike planet. You can buy Dioxite. But you won't always find it at the main Galactic Trade Terminal in a space station.
The trick is to watch the NPC pilots.
Land at a Space Station or a Trading Post and wait for the little shuttle ships to fly in. Walk up to the pilot and check their inventory. Often, pilots in systems with frozen planets will carry stacks of 500 or more Dioxite. It's cheap. Buy the whole lot. If you do this at a few different stations, you can easily bank 5,000 units of Dioxite in ten minutes without ever firing your mining laser.

The Misconception About "Blue" Rocks
A lot of new players see blue crystals and think, "Oh, Dioxite!"
Usually, they’re wrong. Most blue crystals in the game are actually Di-hydrogen, which is what you use for starship fuel. Dioxite rarely appears as those large, jagged surface crystals unless you're on a very specific type of extreme weather planet. Usually, it's buried or hidden inside other minerals. Don't waste your time sprinting toward every blue spark you see on the horizon. Trust your visor instead.
Efficient Storage and Usage
Don't keep Dioxite in your main inventory if you can help it. Put it in your Cargo slots where the stacks are larger. Since the Waypoint update, inventory management has changed, and you want to keep your "recharge" materials in a place where they won't get accidentally sold when you're dumping loot at the terminal.
Also, keep a small amount on your ship. If you're flying through a system and run into a localized storm while on a moon, having that Dioxite ready to go can save you from a very annoying "grave" run.
Actionable Next Steps for Dioxite Farming
Stop wandering and start optimizing. If you need a massive amount of Dioxite right now, follow this specific sequence to maximize your time:
- Find a Frozen World: Scan from space. Look for "Frost Crystals" in the planet's description—that's the ultimate confirmation.
- Locate a Trading Post: Use your Economy Scanner to find a trade hub on the planet surface.
- Check the Pilots: Talk to every ship that lands. Buy their Dioxite. While you wait for the next wave of ships, scan the immediate area for Dioxite deposits.
- Set up a Small Base: If you find a "S-class" Dioxite deposit with your Survey Device, drop a Base Computer and an Atmospheric Extractor. This allows you to passively collect the mineral while you're off doing missions or exploring the center of the galaxy.
- Refine the Rest: If you have Salt and Frost Crystals (which are everywhere on these planets), throw them in a portable refiner while you wait for your ship to refuel.
This approach covers all bases. You're buying, mining, and refining simultaneously. In one twenty-minute session, you’ll have enough Dioxite to last through dozens of hours of gameplay, letting you focus on the actual exploration rather than the constant beep of a failing hazard suit.
