Description

Tantalumrods,99.9% CAS NO 744-25-7 are high-purity metallic rods composed of the refractory metal tantalum. This material is critical for applications demanding exceptional corrosion resistance, high-temperature stability, and excellent biocompatibility. It is an essential component for manufacturers in the chemical processing, aerospace, medical device, and high-tech electronics industries seeking reliable performance in extreme environments.

Application

• Chemical Processing Equipment: Fabrication of heat exchangers, reactor linings, bayonet heaters, and vessels for handling highly corrosive acids like hydrochloric and sulfuric acid.
• Medical Implants and Instruments: Used in surgical tools, bone screws, cranial plates, and other implantable devices due to its excellent biocompatibility and non-reactivity with bodily fluids.
• Aerospace and Power Generation: Manufacture of turbine blades, rocket engine components, and superalloy additions for parts exposed to extreme heat and stress.
• Electronics and Semiconductors: Sputtering targets for thin-film deposition, and as a material for high-capacitance anodes in miniaturized capacitors (tantalum capacitors).
• High-Temperature Furnace Components: Construction of heating elements, radiation shields, and support fixtures in vacuum and inert atmosphere furnaces.
• Laboratory and Research: Used in analytical instrument components and crucibles for high-purity melting processes.

Quality Control

Our high-purity tantalum rods are produced and tested to meet stringent industry specifications. Each batch undergoes comprehensive analysis to verify chemical purity, mechanical properties, and dimensional accuracy. A Certificate of Analysis (COA) detailing trace element content (including key impurities like Niobium, Iron, and Tungsten), density, hardness, and microstructure is provided to ensure material consistency and traceability for critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from strong acids and strong oxidizing agents. For long-term storage, maintaining a clean, low-humidity environment is recommended to preserve surface finish.
