High-Purity Tantalum
High-Purity Tantalum Overview
High-purity tantalum generally refers to metallic tantalum with a purity of ≥ 99.95% (4N5).
Among them, high-purity grades (such as 5N, 6N, that is, purity of 99.999% and 99.9999%) have an irreplaceable role in high-end industrial fields due to their extremely low impurity content (mainly controlling oxygen, nitrogen, carbon, hydrogen and metallic impurities such as iron, nickel, titanium, etc.).
Its preparation requires multiple complex processes such as "purification of tantalum concentrate (e.g. solvent extraction), preparation of tantalum sponge (e.g. sodium reduction), vacuum arc melting / electron beam melting, and precision processing (e.g. forging, rolling)" to reduce the impact of impurities on performance.
High-purity tantalum is a "highly customized performance" strategic metal material.
Its core value lies in achieving precise matching of "corrosion resistance, high-temperature resistance, electrical properties, and biocompatibility" by controlling the purity (from 4N5 to 6N), thereby supporting the technological upgrading of high-end industries such as electronics information, semiconductors, aerospace, and medical care.
Due to its complex preparation process (difficult to purify and high processing costs), and the fact that its global reserves are concentrated (mainly distributed in Australia, Brazil and Canada).
High-purity tantalum has also been listed as a "critical strategic mineral" by many countries. Its technological breakthrough is of great significance to the security of the industrial chain.
High-Purity Tantalum Properties
The properties of high-purity tantalum stem from its unique atomic structure (atomic number 73, body-centered cubic lattice) and extremely low impurity content, mainly manifested in the following five core advantages:
1. In the field of electronic information: The core is "high-performance capacitors"
2. Outstanding high-temperature resistance and thermal stability
3. Excellent physical properties: A balance between thermal conductivity, electrical conductivity and machinability
4. Unique electrical and dielectric properties
5. Biocompatibility (Specific Purity Specifications)
