01 / The challenge

High-temperature systems depend on salt chemistry.

Molten salts offer unique properties that make them attractive for demanding high-temperature applications. However, impurities and uncontrolled chemistry can significantly increase corrosion and accelerate materials degradation.

Controlling salt chemistry can help maintain system performance, reliability, and asset life. SaltGen provides high-purity, low-corrosivity halide salts designed to help reduce corrosion and support longer-lasting, higher-performing systems.

Impurities, composition, redox conditions, and other chemical variables can influence:

  • Materials compatibility
  • Corrosion and degradation
  • Heat transfer
  • Electrochemical behavior
  • Process efficiency
  • Measurement accuracy
  • Long-term system performance
