Every animal has a closely maintained potassium level and a relatively fixed potassium-sodium ratio.

The natural radioactivity of potassium is due to beta radiation from the potassium-40 isotope (10sylvite in Saskatchewan, Canada, provide more than 25 percent of the world’s needs.

The other chief sources of potash are Germany, Russia, Belarus, India, Chile, and Israel.

Modification of the system by the addition of sodium results in a ternary eutectic melting at approximately −78 °C (−108 °F).

The composition of this alloy is 3 percent sodium, 24 percent potassium, and 73 percent cesium.

The alloy is also used as a catalyst or reducing agent in organic synthesis.

In addition to the alloys of potassium with lithium and sodium, alloys with other alkali metals are known.

Too little or too much potassium in the body is fatal; however, potassium in the soil ensures the presence of this indispensable element in food.
