| | Dipotassium hexachloroiridate Usage And Synthesis |
| Chemical Properties | Black Crystalline Powder | | Uses | Black pigment (porcelain decoration). The iridium (III) salt is also known: K3IrCl6, greenishyellow. | | Uses | Iridium potassium chloride (K2IrCl6) is used as a black pigment to make black porcelain
kitchen and bathroom fixtures. | | Uses | Potassium Hexachloroiridate(IV) is a reagent with biocatalytic activity | | Purification Methods | Crystallise it from hot aqueous solution containing a few drops of HNO3 to keep it in the oxidised state. It forms small shiny red-black octahedral crystals which are dried at 100o and give a red powder on grinding [Grube in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol II pp 1593-1594 1965]. |
