Product Details ofTantalum Pellets
Overview
Tantalum pellets, also known as Tantalum granules, are high-purity materials manufactured from fine tantalum powder using advanced cold pressing or Cold Isostatic Pressing (CIP) technologies. As members of the class of rare refractory metals, they are widely used as high-purity tantalum pellets for thin-film deposition in semiconductor diffusion barriers, precision optical coatings, and surface modifications for medical implants.
With more than 20 years of experience in manufacturing and supplying high-purity tungsten, molybdenum, and tantalum products, FANMETAL provides tailored solutions to match your specific process requirements. We offer custom dimensions for tantalum pellets, Tantalum Round Sheet, and Tantalum Rod.

Features of Tantalum Pellets
Tantalum pellets boast outstanding physical and chemical properties, which make them widely adopted in high-end industrial fields. The main characteristics are as follows:
Extremely High Melting Point
Tantalum has a melting point of up to 3017°C. It does not soften or volatilize easily at high temperatures, making it ideal for processes such as vacuum electron beam evaporation and high-temperature sintering. The coating process is stable and resistant to sputtering.
Excellent Corrosion Resistance
It resists corrosion from the vast majority of strong acids, strong alkalis, and organic solvents at room temperature, making it widely applicable in the chemical, electronics, and corrosion-resistant coating industries.
Excellent Electrical and Thermal Conductivity
It offers good electrical and thermal conductivity and provides high process stability when used as a raw material for electronic coatings and capacitor sintering.
Chemically stable and resistant to oxidation.
At room temperature, it passivates in air and humid environments, forming a dense oxide film that makes it resistant to rust and deterioration; it can be stored for long periods under vacuum-sealed conditions.
What are tantalum Pellets used for?
High-purity tantalum pellets are an essential raw material in high-tech industries, valued for their high melting point, exceptional corrosion resistance, stable electrical properties, and excellent biocompatibility. Key applications include:
1. Vacuum Evaporation & Semiconductor Coating
Tantalum pellets serve as premium evaporation sources for optical thin films, semiconductor wafer deposition, hard tool coatings, and decorative films. Uniform particle sizing ensures a stable feed rate, prevents material splattering, and minimizes coating defects.
2. Tantalum Capacitors
We supply tantalum pellets for manufacturing miniature, high-reliability tantalum electrolytic capacitors, which are widely used in automotive electronics, telecommunications, industrial controls, and consumer hardware.
3. Medical Devices & Implants
Due to its outstanding biocompatibility and non-toxic, bio-inert properties, our tantalum pellet is ideal for orthopedic implants, dental restorations, and bio-coatings or surface modifications for medical instruments.
4. Aerospace Superalloys
As a critical alloying element, tantalum improves the high-temperature strength, creep resistance, and oxidation resistance of nickel-based superalloys used in aircraft engine turbines and military defense components.
5. Chemical Processing Equipment
Tantalum withstands extreme acid and alkali environments. Our tantalum pellets are used to smelt corrosion-resistant alloys for lining chemical reactors, piping systems, and laboratory hardware.
6. R&D and Sputtering Targets
We keep supplying high-purity tantalum pellets to university laboratories and new material enterprises. Clients use these raw materials to develop new alloy formulas, test metal physical properties, and melt customized tantalum sputtering targets for thin-film research.

FAQ
Q: Why is tantalum so valuable?
A: Tantalum is rare in nature, with complicated mining and refining processes. Its unique corrosion resistance, high melting point, and great biocompatibility make it nearly irreplaceable in electronics, aerospace, and medical industries, leading to its high value.
Q: Are there application differences between tantalum pellets of different purities?
A: Yes. Low-purity tantalum pellets are mostly used for alloy smelting and general industrial anti-corrosion fields. High-purity grades (99.95%/99.99%) are required for vacuum evaporation, semiconductors, medical implants, and precision electronic components to avoid impurity contamination and guarantee stable performance.
Q: Can I customize the particle size of tantalum granules?
A: Yes. We support custom particle size screening, along with surface treatment and impurity control to match your application requirements.
Q: Do you provide surface polishing treatment for tantalum pellets?
A: Yes, we offer surface polishing and oxide removal treatments for tantalum pellets to prevent splashing and impurity contamination during vacuum evaporation.
Q: What's your delivery time?
A: Our shipping method is mainly by air or sea. After the product is finished, we will use wood, plastic, or carton boxes for tight packaging, and also put some soft materials to prevent product damage. We will deliver it to you as soon as possible, within 20-30 days.
Q: What is your shipping cost?
A: This mainly depends on the weight, volume, the distance from the destination, and the size of the package. We will try our best to communicate with the express company to help you get the most reasonable shipping cost.
