Application:
1. Iridium is the only precious metal thermocouple that can measure temperature up to 2100 C in the atmosphere because of its high temperature oxidation resistance and thermoelectric properties. Iridium can be used as a container material for radioactive heat source. Iridium anodic oxide film is a promising electrochromic material. Ir192 is a gamma ray source, which can be used for nondestructive testing and radiochemical therapy. Iridium is also an important alloying element;
2. Iridium powder/Iridium gold melting into gold can increase the weight, hardness and density of gold, generally adding about 5%~30%(K gold) of gold weight for mixed melting;
3. It is used for electronic pastes, reduce the sintering temperature of the electronic pastes;
4. It is used for welding of alloy, reduce the alloy melting point;
5. It's for in the alloy, improve the abrasion resistance of alloy;
6. It's for lubricants, improve the wear resistance of lubricating oil;
7. In the application of coatings, improve transparency and abrasion resistance, resistance to scratch and conductive ability;
