Tantalum Metal Ta CAS 7440-25-7 For Tantalum Capacitor And Tantalum Crucible

Tantalum is a rare metal with high melting point, strong corrosion resistance and excellent physical properties. In the field of electronics, tantalum capacitors are widely used in communication, computer and aerospace equipment because of their high capacitance and low leakage. In the medical field, tantalum is made into orthopedic implants and medical devices such as cardiac pacemakers due to its good biocompatibility. In addition, tantalum is also used in the manufacture of aircraft engine parts, chemical reactors, etc., showing its excellent performance in high temperature and corrosive environments.

    Tantalum Metal Ta CAS 7440-25-7 For Tantalum Capacitor And Tantalum Crucible

    Name: Tantalum Metal, Tantalum powder
    Molecular formula: Ta
    CAS: 7440-25-7
    Molecular weight: 180.95

    Description

    Tantalum mainly exists in tantalite and coexists with niobium. The hardness of tantalum is moderate and it is malleable. It can be drawn into thin foil of filament type. Its coefficient of thermal expansion is very small. Tantalum has excellent chemical properties and high corrosion resistance. It does not react with hydrochloric acid, concentrated nitric acid and aqua regia under cold and hot conditions. Tantalum is the 51st and richest element on earth. Although it is free, it is usually mixed with other minerals and can be obtained by heating potassium tantalum fluoride or molten salt of electrolytic tantalum.

    Used         

    Tantalum and its alloys are used in the construction of reactors, vessels and crucibles. Tantalum can be used as a substitute for stainless steel in the production of various inorganic acids, and its service life can be dozens of times longer than that of stainless steel. Tantalum has good ability of absorbing impurity at high temperature, and the tantalum oxide film is stable and has good rectifying and dielectric properties. Tantalum is used to make electrolytic capacitors and vacuum furnace parts.
