Iridium Crucible Applications

  • High-Temperature Melting and Holding: Iridium crucibles are ideal for melting and holding metals with high melting points, such as gold, platinum, and other precious metals, due to their ability to withstand extreme temperatures (over 2400°C).
  • Chemical Reactions and Synthesis: Iridium’s high chemical stability makes it suitable for conducting high-temperature chemical reactions and the synthesis of various compounds, especially those involving aggressive chemicals.
  • Material Testing and Research: These crucibles are extensively used in material science for experiments that require high temperatures and inert conditions, such as testing new materials, alloys, and compounds.
  • Nuclear Industry: Iridium crucibles are employed in the nuclear industry to handle and contain radioactive materials due to their excellent resistance to corrosion and radiation.
  • Analytical Laboratories: In labs that involve high-precision analysis and need to maintain inert conditions, iridium crucibles are used for burning and analyzing samples without contamination from the container.

Iridium Crucible Packaging

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

We carry a wide variety of iridium products in stock, and for these, there is generally no minimum order requirement. However, for custom orders, we typically set a minimum order value of $200. The lead time for stock items is usually 1-2 weeks, while custom orders usually take 3-4 weeks, depending on the specifics of the order.

DFARS (Defense Federal Acquisition Regulation Supplement) compliance is primarily concerned with the sourcing of materials for defense-related applications in the United States. According to DFARS, certain materials used in defense must be sourced from the United States or qualifying countries.

If you have specific iridium materials that are subject to DFARS, please let us know in advance and we will confirm.

At Heeger Metal, we take this responsibility seriously. We adhere to all applicable laws and regulations, including Section 1502 of the Dodd-Frank Act. Our company operates with a strict code of ethics and is committed to only partnering with suppliers who share our dedication to responsible sourcing. We support the initiatives and programs aimed at promoting “conflict-free” supply chains and work diligently to ensure that our products meet these standards.

Iridium crucibles are primarily used for high-temperature applications (up to 2400℃), such as crystal growth, semiconductor processing, and chemical analysis due to their extreme corrosion resistance.

Iridium has a higher melting point (2466℃ vs. 1768℃) and better resistance to chemical attack, especially in oxidizing environments.

Heeger Metal, established in 2016 in Colorado, USA, is a specialized supplier and manufacturer of iridium products. With extensive expertise in supply and export, we offer competitive pricing and customized solutions tailored to specific requirements, ensuring outstanding quality and customer satisfaction. As a professional provider of refractory metals, specialty alloys, spherical powders, and various advanced materials, we serve the research, development, and large-scale industrial production needs of the scientific and industrial sectors.
