General description

Magnesium chloride hexahydrate is a highly water soluble crystalline solid widely used in nanomaterial synthesis and thermal energy storage.

Application

Magnesium chloride hexahydrate can be used:
  • As a precursor to synthesize magnesium hydroxide nanoparticles for flame retardant applications.
  • As magnesium source to prepare hydroxyapatite nanoparticles for biomedical application.
  • To fabricate phase change materials for passive thermal control of lithium-ion batteries.
