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.

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.

Our products
Sodium Nitrate
Sodium nitrate (NaNO3) is obtained by leaching caliche ore. It is used preferentially to produce glass, ceramic, explosives and metal treatments.
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.
Potassium Chloride
Its formula is KCI, and its main application is as a stabilizer for oil drilling.
Sylvinite
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.
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.
Use and Applications of Solar Salt
Solar salts are a fundamental component in the production of thermosolar power. Manufactured by SQM, this product is the thermal storage medium used to generate clean power with guaranteed energy continuity 365 days a year. Join us to discover how a thermosolar power plant works.
