• "This is called the eutectic point and any concentration of salt above or below this point will result in a solution with a freezing point higher than - 6°F."
• "In the freeze-drying process, vitrification (also termed eutectic solidification) occurs in the unfrozen fraction between the ice crystals which are sublimated in an endothermic process."
• "Liquid metal (Pb or Pb-Bi eutectic) cooling is at low pressure by natural convection (at least for decay heat removal)."
