Iridium crucible
Everyone is watching
Re≥35% purity: 99%<br>
Nature: dark red or purple crystals. The melting point is 727°C. The boiling point is 800～850℃. Vacuum sublimation at 500℃, the vapor is green. Soluble in water, acid, alkali, liquid ammonia and ethanol, slightly soluble in ether.
Rhodium trichloride, also known as rhodium chloride, is a reddish-brown powder, easily deliquescent. poisonous! The molecular weight is 209.26 (anhydrous), and the melting point is 450-500°C (decomposition). Boiling point is 800℃ (sublimation). To produce polyfluoride above 600 ℃. It can be reduced by hydrogen at 70°C. It is insoluble in water, acid and aqua regia, but soluble in methanol and cyanide solution. Decompose by heating in concentrated acid (nitric acid, sulfuric acid). It can interact with metals such as sodium, aluminum, magnesium and iron when heated.
<br>
Used in electronics, instrumentation, metallurgy and other industries, also used in electroplating operations, catalyst preparation.
Product name: Pt≥58.0% PtN2O6<br>
Properties: Platinum nitrate refers to an orange-brown powder chemical substance
Purity: 3N5<br>
Size: 1-10 inches, unconventional size can be customized<br>
Application
The high temperature oxidation resistance and thermoelectric properties of iridium make the iridium/iridium rhodium thermocouple the only precious metal temperature measurement material that can measure high temperatures up to 2100℃ in the atmosphere.
Ir≥99.95%<br>
Size: diameter D (1-20) * height H (10-15) mm; if the buyer has special requirements for size and unit weight, the two parties agree to order<br>
Application: mainly used for evaporating coating materials
Iridium crucible (diameter Φ50~300mm, height 40~400mm)<br>
Application:the iridium crucible can be used to grow refractory oxide crystals. The crucible can work at 2100-2200°C for thousands of hours and is an important precious metal vessel material. The high temperature oxidation resistance and thermoelectric properties of iridium make the iridium/iridium rhodium thermocouple the only precious metal temperature measurement material that can measure high temperatures up to 2100℃ in the atmosphere; iridium crucibles can be used as a container material for radioactive heat sources.
