Platinum Crucible Description

Platinum (Pt) is a grayish-white precious metal with high density, high ductility, and low reactivity. It is a transition metal. Platinum Crucible is made from high-purity platinum with a 99.95% or 99.99% purity. It is produced with strict quality control, ensuring high consistency, uniformity, and performance in every batch. It has exceptional durability, resistance to corrosion, and stable performance even under extreme conditions. It is ideal for melting, refining, and processing metals, as well as for conducting high-temperature reactions and sample preparations. Heeger Metal can supply high-quality platinum crucibles in various sizes and customized designs for multiple industrial and research applications.

Platinum Crucible Applications

  • Chemical Analysis: Used in laboratories for conducting high-temperature reactions and sample preparations, especially in elemental analysis and material testing.
  • Metallurgical Processes: Employed for melting, refining, and alloying metals due to platinum’s ability to withstand extreme temperatures.
  • Sintering: Used in the sintering of powders and ceramics, where high thermal stability is required.
  • Evaporation Processes: Used in vacuum evaporation to deposit thin films of metals and other materials.
  • Pharmaceutical Industry: Utilized in the preparation of compounds and in processes that require precise temperature control and high purity.
  • Glass Manufacturing: Platinum crucibles are used in glass manufacturing processes, particularly for producing high-quality and specialized glass.
  • Catalysis: Platinum crucibles serve as reaction vessels in catalysis, especially for reactions that involve high temperatures.

Platinum Crucible Packaging

Platinum 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.
