Tantalum target is usually welded with the copper back target, and then semiconductor or optical sputtering is carried out to deposit tantalum atoms as oxides on the substrate material to achieve sputtering coating.

Tantalum has the characteristics of low elastic modulus, high friction coefficient, excellent tissue endogeneity and cartilage conductivity, high strength, strong corrosion resistance, and outstanding biocompatibility. It is an ideal human bone substitute material.

Nano tantalum powder is produced by a variable current laser ion beam gas phase process, with high purity, uniform particle size, complete surface structure, easy dispersion, large specific surface area, and high surface activity. The density of nano tantalum powder is 16.5g/cm3, and the melting point is 2800 degrees. Tantalum capacitors are capacitor products used in the field of military electronics. The size of electronic products has become smaller and smaller, requiring the development of tantalum capacitors in the direction of miniaturization and high capacity. The specific capacity of micron tantalum powder is closely related to the particle size density. The smaller the size, the larger the specific capacity. Therefore, the preparation of nano-tantalum powder promotes the development of tantalum capacitors.

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.

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.

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.
