Potassium Hexachloroiridate(III) is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered.American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia)and follows applicable ASTM testing standards.Typical and custom packaging is 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 number of electrons in each of Potassium's shells is 2, 8, 8, 1 and its 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 not toxic. 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. Potassium also used as a nutrient in plant growth. Potassium was first discovered by Sir Humphrey Davy in 1807. The origin of the element name comes from the English word 'potash' meaning pot ashes and the Arabic word 'qali' which means alkali. The symbol K originates from the Latin word 'kalium'. See Potassium research below.
Iridium is a Block D, Group 9, Period 6 element. The number of electrons in each of Iridium's shells is 2, 8, 18, 32, 15, 2 and its electronic configuration is [Xe] 4f14 5d7 6s2. In its elemental form iridium's CAS number is 7439-88-5. The iridium atom has a radius of 135.7.pm and it's Van der Waals radius is 200.pm. Iridium is only slightly toxic. Iridium is a member of the platinum group of metals. It is the most corrosion resistant metal known. It will not react with any acid and can only be attacked by certain molten salts, such as molten sodium chloride. It is alloyed with platinum to produce highly corrosive resistant electrical contacts for spark plugs. Iridium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. Iridium information, including Technical Data, Safety Data and its high purityproperties, research, applications and other useful facts are discussed here. Iridium was first discovered by Smithson Tennant in 1804. See Iridium research below.
