Application of metal material tantalum

Application of metal material tantalum

The tantalum target is usually called a bare target. First, it is welded with a copper back target, and then semiconductor or optical sputtering is performed, and tantalum atoms are deposited on the substrate material in the form of oxide to realize sputtering coating; in the semiconductor industry At present, metal tantalum (Ta) is mainly used as a target material through physical vapor deposition (PVD) coating and formation of a barrier layer.

As we all know, although the performance of metal tantalum is relatively stable, metal tantalum powder with relatively fine particle size is relatively active, and reacts with oxygen and nitrogen at room temperature, which increases the content of impurities such as oxygen and nitrogen in tantalum powder. In order to obtain a high-quality tantalum target, the impurity content in the tantalum powder must be reduced first, and the purity of the tantalum powder must be increased. Reducing the particle size of tantalum powder is very necessary to improve the quality of tantalum powder and tantalum target.

Tantalum targets are mainly used in semiconductor coating, optical coating, decoration, flat panel display, functional coating, and other optical information storage space industries, glass coating industries such as automotive glass and architectural glass, and optical communications.

Semiconductor

Using a physical vapor deposition (PVD) process, a tantalum sputtering target is “sputtered” onto the semiconductor substrate to form a thin film diffusion barrier to protect the copper interconnects. Tantalum sputtering targets are also used in a variety of other products, including magnetic storage media, inkjet printer heads, and flat panel displays.

engine turbine blades

High melting point and corrosion resistance properties make it well suited for alloying applications. Tantalum is used in nickel-based superalloys, mainly in turbine blades for aircraft engines and land-based gas turbines.

chemical processing equipment

Extremely high resistance to corrosion and high temperatures makes the metal an ideal material of construction for linings of vessels, pipes, valves and heat exchangers in the chemical and pharmaceutical industries.
