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.

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

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

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

Sylvite 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.

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.

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