Niobium Sputtering Target Production Process

Generally prepared by powder metallurgy method, the purity of niobium powder should be above 99.95%. The specific process is as follows:

  • Put the niobium powder in the vacuum heat treatment furnace for pre-gassing, then introduce hydrogen and continue heating for degassing.
  • The degassed niobium powder is sintered once by vacuum hot pressing.
  • The primary sintered product is passed through a hot isostatic press to complete the secondary sintering.
  • After the secondary sintering, the whole surface of the product is ground by machining to get the final product.

Niobium Sputtering Target Applications

  • Flat Panel Displays and Liquid Crystal Displays: Niobium sputtering targets are used to manufacture high-quality displays that provide clear images and high contrast.
  • Optical Lenses: In optical devices, niobium sputtering targets are used for coating to improve light transmission and durability.
  • Solar Cells: Niobium sputtering targets are also used to produce solar cells to improve photovoltaic conversion efficiency.
  • Glass Coating: Niobium sputtering targets are used in the surface coating of energy-saving glass with anti-reflective and heat-insulating properties.

Niobium Sputtering Target Packaging

The Niobium Sputtering Target is carefully placed in wooden cases or cartons with additional support from soft materials to prevent any shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.
