Potassium 40 Chloride (Potassium-40) is a stable (non-radioactive) isotope of Potassium. See below table for ENSDF Citation and Half Life. It is both naturally occurring and produced by fission. Potassium 40 Chloride is one of over 250 stable isotopes produced by American Elements for biological and biomedical labeling, as target materials and other applications. Potassium Chloride is also available in ultra high purity and as nanoparticles. For thin film applications it is available as rod, pellets, pieces, granules and sputtering targets and as either an ingot or powder. Potassium Chloride 40 isotopic material is generally immediately available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.

Potassium is a Block S, Group 1, Period 4 element. The electronic configuration is [Ar] 4s1. In its elemental form potassium's CAS number is 7440-09-7. The potassium atom has a radius of 227.2 .pm and it's Van der Waals radius is 275.pm. Potassium is the seventh most abundant element on earth. In its metallic form it is one of the most reactive and electropositive of all metals and rapidly oxidizes. As with other metals of the alkali group, the metal decomposes in water with the evolution of hydrogen. It catches fire spontaneously in water. In high purity, potassium compounds have numerous pharmacological, medical, and electronics applications. Important compounds include the hydroxide, nitrate, carbonate, chloride, bromide, iodide, and sulfate. Lower purity compounds are used in pyrotechnics for its violet color on ignition and in glass and ceramic glazes to produce this color.
