Manufacture process of R05200 Ta foil Tel：0917-3664600
R05200 is a high-purity tantalum foil with a purity of 99.95% or higher. The manufacturing process of R05200 Ta foil typically involves the following steps:
Raw Material Preparation: The first step is to prepare the raw material, which is tantalum ore. The ore is typically processed into tantalum powder through a series of chemical and physical processes such as crushing, grinding, and chemical treatment.
Powder Production: The tantalum powder is then pressed into blocks or bars and sintered at high temperatures to create a solid piece of tantalum metal. The resulting tantalum block is then rolled into thin sheets or foils using a rolling mill.
Annealing: The tantalum foil is annealed to remove any residual stresses and to improve its ductility. The annealing process involves heating the foil to a high temperature and then cooling it slowly to room temperature.
Cutting and Finishing: The tantalum foil is then cut into the desired size and shape using precision cutting tools such as laser cutters or water jet cutters. The edges of the foil are then finished and polished to ensure a smooth and uniform surface.
Inspection and Quality Control: The final step is to inspect the tantalum foil for defects such as cracks, pinholes, or surface imperfections. The foil is also subjected to various quality control tests to ensure its purity, thickness, and mechanical properties meet the required specifications.

Packing And Shipping Tel：0917-3664600
Packaging: Cardboard boxes or wooden crates
1. Inner Packaging: Mandrel and Wrapping
Roll: Tantalum foil is wound onto a rigid plastic cylinder. This prevents the foil from being creased or deformed during storage and transportation.
Wrapping: The wound tantalum foil is first wrapped in moisture-proof soft paper, then sealed with a layer of plastic film. This plastic film is a key moisture barrier, effectively isolating moisture from the air.
2. Outer Packaging: Wooden Crate or Cardboard Box and Filling
Boxing: The inner-wrapped tantalum foil roll needs to be placed in a wooden crate.
Liner: The inside of the wooden crate or cardboard box must be lined with moisture-proof paper to provide further moisture protection.
Securing: To prevent shaking and collisions during transportation, gaps inside the box need to be filled with soft material to ensure the tantalum foil is securely held within the box.
Shipping: Express, air freight, or sea freight
Express: 5-7 days
Air freight: 3-4 days
Sea freight: 15-30 days
FAQ
Q: 1. Will tantalum foil deform at high temperatures?
A: The low-temperature expansion coefficient of tantalum foil enables it to maintain its dimensional stability in different temperature ranges and is not prone to deformation and cracking. Tantalum foil has a wide range of applications. In the aerospace field, tantalum foil is often used to manufacture engine components, fuel rods, and high-temperature structural parts.
Q: 2. Will tantalum foil oxidize?
A: The oxidation of tantalum foil mainly occurs in high-temperature and high-humidity environments, and oxygen and moisture are the main causes of its oxidation. Under such conditions, a dense tantalum pentoxide (Ta2O5) film will form on the surface of the tantalum foil. This oxide film has good chemical stability and insulation properties.
The oxidation of tantalum foil has an important impact on its performance and service life. On the one hand, the formation of the oxide film can improve the chemical stability and electrical insulation properties of tantalum foil, and protect it from damage such as corrosion and electric shock. On the other hand, the thickening of the oxide film will increase the resistance of the tantalum foil and affect its conductivity. Therefore, in practical applications, it is necessary to control the thickness of the oxide film according to specific needs to balance protection and conductivity.

Q: 3. Will titanium foil corrode?
A: Tantalum also has excellent chemical properties and is highly resistant to corrosion. It does not react to hydrochloric acid, concentrated nitric acid, or "aqua regia" under cold or hot conditions. However, tantalum can be corroded in hot concentrated sulfuric acid. Below 150°C, tantalum will not be corroded by concentrated sulfuric acid. It will only react at a temperature higher than this. After being exposed to concentrated sulfuric acid at 175°C for one year, the thickness of the corroded surface is 0.0004 mm. After being immersed in sulfuric acid at 200°C for one year, the surface is only damaged by 0.006 mm.
Tantalum can also be corroded by phosphoric acid at high temperatures, but the reaction generally occurs above 150°C. After being immersed in 85% phosphoric acid at 250°C for one year, the surface is corroded by 20 mm. In addition, tantalum can be quickly dissolved in a mixed acid of hydrofluoric acid and nitric acid, and can also be dissolved in hydrofluoric acid.

Q: 4. What are the core performance advantages of tantalum foil?
A: There are three main points: 1) Extremely strong corrosion resistance; it is almost completely unreactive to most strong acids (hydrochloric acid, nitric acid, etc.) at room temperature; 2) Extremely high melting point (approximately 2996℃), and good high-temperature strength; 3) Excellent dielectric properties; its surface oxide film is stable, which is the foundation for manufacturing high-end capacitors.
Q: 5. Why is ultra-thin tantalum foil (<0.05mm) prone to breakage during production?
A: The main reason is improper rolling tension control. The thinner the foil, the more sensitive it is to tension fluctuations. Excessive tension will cause breakage, while insufficient tension will lead to misalignment and wrinkling. In addition, the uneven microstructure of the raw material can also lead to localized stress concentration and breakage.
Q: 6. What are the uses of tantalum foil in 5G and new energy vehicles?
A: It is mainly used as a core material for tantalum capacitors. The electronic control systems of 5G base stations and new energy vehicles have extremely high requirements for the stability and high-temperature resistance of capacitors, and tantalum capacitors are one of the preferred components to meet these stringent requirements.
