Chinese name: iridium crucible
Density: not less than 21g/CM3
Leakage: no leakage is allowed
USES: artificial crystal industry, artificial gem, sapphire long crystal method. Iridium crucible refractory oxide crystal growth which can be used, the crucible can thousands of hours in 2100 ~ 2200 ℃, material is an important precious metal vessels. High temperature oxidation resistance and thermoelectric properties of iridium make iridium/it rhodium thermocouple can be measured in the atmosphere only precious metal temperature of 2100 ℃ high temperature materials; The iridium crucible can be used as a container material for radioactive heat sources.
Raw material standard: the raw material used for iridium crucible shall meet the requirements of GB/T 1422 iridium powder purity not lower than sm-ir99.95 brand.
Surface quality: the surface should be smooth and clean. No sand inclusion, crack or sand hole defect; It is allowed to have local pits whose depth does not affect the use, and it is allowed to have weld marks.
Characteristics of rolled and welded iridium crucible:
1. The surface is smooth and smooth, and the internal structure is dense, which eliminates the defects such as porosity, porosity and interlayer existing in the cast iridium crucible, and significantly improves the service life of the cast iridium crucible.
2. Uniform wall thickness, suitable for symmetrical temperature field required by crystal growth.
3, Can process large size, shaped, thin - walled iridium crucible.
4, Easier maintenance, plastic, repair welding, saving remanufacturing costs.
5. Crucible of the same size should save about 30% iridium compared with casting crucible. In line with national standards: gb1597-2004
