Tantalum Sheet & Tantalum Plate Description

Tantalum Sheets and Tantalum Plates are crafted from high-purity tantalum, a dense, ductile, and highly corrosion-resistant metal with a distinctive dark blue-gray appearance. Known for its exceptional resistance to chemicals at temperatures below 150°C, tantalum can only be dissolved by hydrofluoric acid. With a high melting point and the ability to form an ultra-thin, protective oxide layer, tantalum is an ideal material for high-performance capacitors and advanced industrial applications.

With over 20 years of expertise in tantalum manufacturing and sales, Stanford Advanced Materials (SAM) is a globally trusted supplier of high-quality Tantalum Sheets and Tantalum Plates. We offer reliable and competitively priced tantalum products tailored for various industries.

Tantalum Sheet & Tantalum Plate FAQs

Q1: Why is tantalum treated in a vacuum during heat treatment?

Tantalum reacts actively with oxygen, so it is crucial to avoid exposure to even a small amount of air during heat treatment. This is why almost all heat treatment processes for tantalum are conducted in high vacuum environments, ensuring minimal oxidation and maintaining the material’s purity.

Q2: What is the typical heat treatment temperature for tantalum?

The heat treatment temperature for tantalum typically ranges from 950°C to 1300°C. This range ensures that tantalum and its commonly used alloys do not undergo phase transitions, and the process is primarily intended for annealing. The temperature and cooling rate are not critical, but a slightly extended time helps achieve complete recrystallization.

Q3: How should Tantalum Sheets be stored?

Tantalum Sheets should be stored in a cool, dry place to prevent contamination or damage. They should be kept in a controlled environment to avoid exposure to moisture or reactive gases.

Raw Materials-Tantalite

Tantalum is a rare metal, constituting only 0.0002% of the Earth's crust, and is commonly found in nature alongside niobium. Although many minerals contain tantalum, only a few qualify as tantalum ores (Ta/Nb ≥ 1). The main industrially valuable tantalum minerals include tantalite [(Fe, Mn)(Ta, Nb)2O6], ferrotantalite (FeTa2O6), microlite [(Na, Ca)Ta2O6(O, OH, F)], and columbotantalite [(Y, Ca, Ce, U, Th)(Nb, Ta, Ti)2O6].

As a professional U.S. supplier of Tantalum Products, Stanford Advanced Materials carefully selects high-quality tantalum ore from around the world to ensure superior purity and performance. We primarily source high-grade tantalite from Australia, one of the world's largest tantalum producers, known for its stable supply and advanced mining technology. Additionally, we prioritize sustainability in mineral sourcing and work with suppliers that comply with Conflict-Free Minerals standards to ensure transparency and regulatory compliance in our supply chain.
