Chinese name: Iridium crucible

Density: not less than 21g/cm3

Leakability: No leakage is allowed.

Uses: Artificial crystal industry, artificial gemstones, sapphire long crystal method. Iridium crucible can be used to grow refractory oxide crystals. The crucible can work for thousands of hours at 2100~ 2200 ° C. It is an important precious metal vessel material. The high temperature oxidation resistance and thermoelectric properties of iridium make iridium/iridium rhodium thermocouples the only ones that can measure high temperatures up to 2100 ° C in the atmosphere

Precious metal temperature measuring material; Iridium crucible can be used as container material for radioactive heat source.

Raw material standards: The raw materials used in the iridium crucible shall meet the requirements of GB/T 1422 that the purity of iridium powder is not less than SM-Ir99.95 grade.

Surface quality: The surface should be smooth and clean. No sand inclusion, cracks, and trachoma defects are allowed; local pits that do not affect the depth of use are allowed, and welding lines are allowed.

Rolling and welding structure Iridium crucible features:

1. The surface is flat and smooth, and the internal structure is dense, eliminating the porosity, pores, interlayer and other defects of the cast iridium crucible, and the service life is significantly improved compared with the cast crucible.

2. The wall thickness is uniform, suitable for the symmetric temperature field required for crystal growth.

3. Can process large-sized, special-shaped, thin-walled iridium crucibles.

4. It is easier to repair, reshape, and repair welding, saving remanufacturing costs.

5. Crucibles of the same size require about 30% iridium savings compared to casting pots. In line with national standards: GB1597-2004
