What Are the Uses of Tantalum?

The tolerance of tantalum to interstitial elements and reasonable elastic modulus make it an attractive base element of the alloy. Tantalum is also easy to achieve the inert gas tungsten arc welding (GTA), so it is suitable for the manufacture of various chemical equipment to give play to its corrosion resistance, such as various heat exchangers, coil tubes, condensing tubes, cooling pipes and insert heaters.

For example, the tantalum sheet in the standard specification of 1.2m x 3.7m x 0.9mm in the Cabot Company has been made of steel, copper, and aluminum through the explosive connection process. It is used to make large and relatively inexpensive chemical equipment.

The so-called explosive connection is usually referred to explosive forming and explosive welding. This is a method of metal connection or processing with high energy released by the explosive in a very short time, a large area of welding or recombination can be achieved between the substrate and the covering layer. It is an effective method to perform special functions such as low cost of the base material, cladding resistance, and high temperature.

In addition, some high-temperature chemical reactions in the vacuum and the melting of special glass are often carried out in tantalum crucible. Tantalum also resists the corrosion of some liquid metal, which used in contact with the liquid sodium of 1375 ℃.

The preparation of tantalum alloying or tantalum group alloy is usually carried out by an electron beam furnace. In order to obtain uniform ingots, the vacuum arc remelting (VAR) is also required after the purification of the electron beam furnace.

All tantalum and its alloy products are cast by electron beam furnace. Whether to use vacuum arc remelting at the same time depends on the use of the product, whether to use vacuum arc remelting at the same time or not depends on the use of the product.

Tantalum alloy is an ideal structural material for working under 1600-1800 ℃ with the lowest brittle-ductile transition temperature (-196), low-temperature plasticity, small working hardening coefficient, and excellent high-temperature strength. At present, there are two alloys of ta-w and ta-nb, which are used to make the components of the aviation industry and space nuclear power system.
