Iridium Powder, Color : Grey, CAS No. : 439-88-5, Purity : 99.95

Pure Iridium metal element, Pt-Ir alloy and  Ir-Rh alloy apply to make scientific instruments, thermocouple and resistive conductor. Adding iridium element in platinum would improve its corrosion resistance in water, acid and halogen and mechanical strength under 500℃。

Many oxide monocrystals of high melting point grow in crucible of pure Ir element. Iridium pieces can process into iridium wires, which is for high temperature antioxidant thermocouple material and filament material.
