You are interested in TU 48−19−258−93 «Foil tantalum and niobium. Technical specifications «from the supplier company AvecGlob? Here you will find the necessary information on this topic.
Application area
These technical specifications apply to tantalum and niobium foils, manufactured according to individually established ranges of dimensions and thickness. The described assortment is used in the following applications:
- For carrying out laboratory studies where resistance against chemical attacks of various media is required under vacuum and high temperatures
- Tantalum and niobium are often used in medical equipment when creating X-ray tubes and other parts of the corresponding equipment. In surgical practice, foil from these metals is used in the manufacture and installation of surgical implants;
- Equipment for the chemical industry, where such foil is used as working components of smoke collection equipment. Any body, pasted with such a foil, will be reliably protected from penetration of gases;
- With decorative shelling of rocket and space equipment, aircraft equipment and instruments.
- In addition, niobium foil is used in nuclear power engineering. The high melting point of niobium guarantees its operability at temperatures above the maximum operating temperature of iron, nickel and cobalt metals. It has excellent plasticity and manufacturability.
Production
The technology for the production of tantalum and niobium foils includes chemical vapor deposition, physical vapor deposition, including evaporation of the thermal and electron beams, low-temperature organic evaporation, deposition of the atomic layer, deposition of metallic organic substances and chemical vapors. As a result of such processes, the strip sequentially crystallizes and passes various cleaning processes, including sublimation. Standard foil sizes vary in thickness from 0.06 mm to 0.8 mm with strict tolerances and normalized conductivity values.
