Industrial Chemicals

We have proven experience producing and selling nitrates, potassium chloride, boric acid and magnesium chlorides. Potassium nitrate and sodium nitrate are the raw materials for solar salts, which are essential to the functioning of solar thermal power plants; and magnesium chloride hexahydrate—known as bischofite—is used for effective dust control and de-icing on roads.

Contributing to the development of the Global Compact SDGs

The iodine produced by SQM is the main component of injectable contrast media for clinical examinations, and is used directly in the production of various drugs, allowing us to be present in health, a strategic industry for human development.

Our products

Solar Salts

Thermo-solar salts are a mixture of 60% sodium nitrate (NaNO3) and 40% potassium nitrate (KNO3). This mixture of salts has chemical properties that make it the ideal solution for storing thermal energy in solar power plants.

More information

Sodium Nitrate

Sodium nitrate (NaNO3) is obtained by leaching caliche ore. It is used preferentially to produce glass, ceramic, explosives and metal treatments.

More information

Potassium Nitrate

Potassium nitrate (KNO3) is obtained through a reaction of NaNO3 and potassium chloride (KCl). It is an important input in the production of crystal, enamel for covering ceramic or metallic surfaces, metal treatments and gun powder, among others.

Potassium Sulfate

Potassium sulfate (K2SO4) is obtained from the brines of the Salar de Atacama and is used to manufacture drywall panels for the construction industry.

More information

Potassium Chloride

Its formula is KCI, and its main application is as a stabilizer for oil drilling.

More information


Sylvinite is one of the salts that naturally precipitates during the evaporation process in the Salar de Atacama. It is a mixed salt containing NaCl and KCl that is used increasingly in the food industry as a low-sodium salt.

Magnesium Chloride Hexahydrate / Bischofite

This product’s chemical formula is MgCl2 + 6H2O and it is one of many derivatives from the brine production process. It is used as a stabilizer, dust control and de-icing agent on roads.

More information

Sodium Chloride

Its formula is NaCl, and it is also known as halite or simply rock salt. It has both industrial and food industry applications.
