Tantalum rod
Explanation: Tantalum metal element mainly exists in tantalite and co-exists with niobium. The texture of tantalum is very hard, the hardness can reach 6-6.5. Its melting point is as high as 2996℃, second only to tungsten and rhenium, ranking third. Tantalum is malleable and can be drawn into a thin wire-like foil. Its coefficient of thermal expansion is very small. It only expands by 6.6% per degree Celsius. In addition, its toughness is very strong, even better than copper. Tantalum also has extremely high corrosion resistance. It does not react to hydrochloric acid, concentrated nitric acid and "aqua regia" regardless of whether it is under cold or hot conditions.

Product description

Explanation: Tantalum metal element mainly exists in tantalite and co-exists with niobium. The texture of tantalum is very hard, the hardness can reach 6-6.5. Its melting point is as high as 2996℃, second only to tungsten and rhenium, ranking third. Tantalum is malleable and can be drawn into a thin wire-like foil. Its coefficient of thermal expansion is very small. It only expands by 6.6% per degree Celsius. In addition, its toughness is very strong, even better than copper. Tantalum also has extremely high corrosion resistance. It does not react to hydrochloric acid, concentrated nitric acid and "aqua regia" regardless of whether it is under cold or hot conditions.

Uses: It can be used to make evaporators, etc., and can also be used as electrodes for electron tubes, rectifiers, and electrolytic capacitors. Tantalum is easy to process and shape. It is used as support accessories, heat shields, heaters and heat sinks in high-temperature vacuum furnaces. It is medically used to make thin sheets or thin threads to repair damaged tissues.

Capacitor grade tantalum powder
Capacitor grade tantalum powder
Description: Metal tantalum powder, the dense oxide film formed on the surface of the powder has the properties of one-way conductive valve metal. The prepared anode film has stable chemical properties (especially stable in acid electrolyte), high resistivity (7.5×1010Ω·cm), high dielectric constant (27.6), and low leakage current. It also has the advantages of wide operating temperature range (-80~200℃), high reliability, shock resistance and long service life. Adopt sodium heat reduction and hydrogen embrittlement method to make powder. Or use 55%KCl-27.5%KF-17.5%K2TaF7 to form molten salt electrolyte to produce tantalum powder. Used to manufacture high-quality electrolytic capacitors . <br> Uses: Military equipment and high-tech fields, such as missiles, space vehicles, televisions, electronic computers, etc.
Tantalum sheet/Tantalum plate
Tantalum sheet/Tantalum plate
Tantalum sheets and tantalum plates can be used to manufacture various inorganic acid preparation equipment, corrosion-resistant fasteners, supporting accessories, heat shields, heaters and heat sinks in high-temperature vacuum furnaces, water tanks, bridges Cathodic protection systems for steel structures.

Niobium rod/ niobium rod/ niobium bar
Note: Niobium can withstand high temperature and high strength, and still has sufficient strength, plasticity and thermal conductivity above 1000°C. Superconductivity is best at extremely low temperatures. For example, its resistance is close to zero at minus 260°C. It is currently the most important superconducting material.
