Niobium foil is a thin sheet material made of niobium metal, with the following main characteristics:

1. Thickness and purity: The thickness of niobium foil is usually 0.127 millimeters (0.005 inches), and after annealing treatment, the purity reaches 99.8% (metal base).

2. Physical properties: Niobium foil has high melting point (2467 ℃), high boiling point (4740 ℃), high specific gravity (8.6), as well as good corrosion resistance, fatigue resistance, deformation resistance, and thermal conductivity.

3. Application areas: Niobium foil is widely used in the electronics industry, chemical processes, high-pressure sodium lamp manufacturing, aviation and aerospace industries, and other fields. For example, niobium foil can be used as a reflective material for high-pressure sodium lamps, reaction vessels for chemical processes, heat exchanger tubes, and internal components of reactors.

The main uses of niobium foil include:

Electronics industry: used in the fields of microelectronics, silicon wafer manufacturing, flat panel displays, and storage technology.

Chemical process: serving as a reaction vessel and heat exchanger tube.

High pressure sodium lamp: a reflective material used to make high-pressure sodium lamps.

Aviation and aerospace industry: structural materials used for aviation and engines.
