Iridium Crucible

Iridium Crucible is produced using high-purity iridium with a content of 99.95% or above. Known for its ability to withstand prolonged use at extremely high temperatures (2100–2200°C), it is essential in growing refractory oxide crystals and is also used as a container material for radioactive heat sources. Thanks to its excellent oxidation resistance and thermoelectric properties at high temperatures, it supports applications such as Ir/Ir-Rh thermocouples—the only noble metal thermocouples capable of measuring temperatures up to 2100°C in air. Heeger Materials offers Iridium Crucibles in sizes ranging from Φ50–300 mm in diameter and 40–400 mm in height, with options to meet specific research and industrial requirements.

• High Purity Material: Made from ≥99.95% iridium, ensuring consistency and performance.
• Excellent Thermal Conductivity: Ideal for precise temperature control in crystal growth.
• Structural Integrity: Maintains shape and strength under extreme thermal cycling.

Iridium Crucible Applications

• Crystal Growth: Used for growing refractory oxide crystals like sapphire or garnet.
• Radioactive Material Containment: Acts as a durable container for radioactive heat sources.
• High-Temperature Furnaces: Support experiments and production under extreme heat.
• Thermocouple Calibration: Applied in Ir/Ir-Rh thermocouples for ultra-high temperature measurement.
• Advanced Material Processing: Used in R&D for high-purity or rare material synthesis.

Iridium Crucible Packing 

The Iridium Crucible will be carefully placed in wooden cases or cartons, with additional support from soft materials, to prevent shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.
