Chloride salts

MgCl₂-NaCl & MgCl₂-NaCl-KCl

Binary and ternary chloride eutectics for fast-spectrum chloride reactor research, thermal storage, and corrosion studies where chloride chemistry — not fluoride — is the relevant environment.

MgCl₂-NaCl

MgCl₂–NaCl

A binary chloride eutectic used as a lower-cost, high-temperature stand-in for chloride-fueled and chloride-cooled reactor concepts, and as a general thermal storage / heat-transfer medium.

450°C
Purity
≥ 99.5% (metals basis); OH⁻ / oxide < 500 ppm; low sulfate
Packaging
Dry-room packed, argon-sealed granulate or ingot, 250 g – 25 kg
Typical applications

MgCl₂-NaCl-KCl

MgCl₂–NaCl–KCl

The lowest-melting common chloride eutectic in the MgCl₂ system, giving the widest liquid-range margin of the chloride salts we carry — useful where minimizing freeze risk in test loops matters as much as reactor relevance.

Composition
≈60 MgCl₂ – 20 NaCl – 20 KCl (mol %)
Melting point
396°C
Purity
≥ 99.5% (metals basis); OH⁻ / oxide < 500 ppm; low sulfate
Packaging
Dry-room packed, argon-sealed granulate or ingot, 250 g – 25 kg
Typical applications
  • Fast-spectrum chloride reactor fuel/coolant simulant
  • Low-melting heat-transfer fluid research
  • Freeze-plug and freeze-valve behavior studies
  • Materials compatibility testing
