Potassium-sodium alloy
  
Sodium Potaddium Al
[Do not] sodium potassium alloy [shrink]JNHJ
Chemical Structure 4K-Na
[chemical properties] glenflange
Silvery soft solid or liquid. Reacts violently with acid, carbon dioxide, moisture, and water, releases hydrogen, spontaneously ignites, and sometimes explodes. Density: 0.847 g/ml (100°C) (K78%, Na22%); 0.886 g/ml (100°C) (K56%, Na44%) Melting point: -11°C (K78%, Na22%); 19°C (K56%, Na44%);
[limit parameters] Boiling point: 784°C (K78%, Na22%); 825°C (K56%, Na44%);
[Application] The coolant used in liquid metal nuclear reactors is a sodium-potassium alloy that is liquid at room temperature.
