Precious metal - 99.95%Iridium Powder
A brief description
Iridium belongs to the group of the periodic table VIII transition elements, element symbol Ir, atomic number 77, atomic weight 192.2, is a kind of rare and precious metal materials. The density is 22.56g/cm3 ,the melting point of 2454 ℃, iridium products using temperature can reach 2100 to 2200 ℃. Iridium, high elastic modulus, Poisson's ratio (538.3GPa) and low (0.26), low temperature ductility is very poor, and other properties. Iridium is the most resistant to corrosion, density of iridium all insoluble inorganic acid, nor by other metal melt erosion. Like other platinum group metal alloy, iridium alloy can be firmly adsorbed organic matter, can be used as catalyst materials. Iridium powder Changsha Ultra Minor Metals Corporation long-term supply of powder, and different size of iridium crucible.
The earliest application of iridium is the tip material, then proposed the use of injection needles, balance blade, compass bracket, electrical contact etc.. Iridium crucible used for growth of refractory oxide crystal and the crucible in 2100 ~ 2200 DEG C thousands of hours of work, is the precious metal ware important materials. The high temperature oxidation resistance and thermoelectric properties of iridium iridium / iridium rhodium thermocouple to measure the temperature as the only precious metal materials up to 2100 degrees Celsius in the air; iridium can be used as a container material radioactive source; anodic iridium oxide film is a promising electrochromic materials. Ir192 is a gamma ray source, can be used for non-destructive testing and treatment of radiation chemistry. At the same time, iridium is a very important alloying elements.
