There are many ways to get sodium nitrate, although there is one way you can get a lot of sodium nitrate in a fairly short time compared to the other ways. This guide will provide the best way to get Sodium Nitrate in No Man’s Sky.
First, you need to find a planet with water, like big, medium-sized lakes or even oceans.
Once you find a planet, head near any of the water sources you find on the planet and look for crystal sulphide in the water sources.
Once in the water, you need to look for small rock formations. Normally, they will glow to find crystal sulphide, and you can harvest it off the sides of the rock. You can normally get about 3 crystals for each rock, equal to about 150 sodium nitrate.
Once you have some crystal sulphide, all you are going to do is put it into a refiner and refine it into sodium nitrate. You will get 50 sodium nitrate for one crystal. You can get 1000+ in a pretty short time with this method.
Here are the portal coordinates for the planet.
