SAM’s Tungsten Boride Sputter Targets are available in various forms, purities, sizes, and prices. We specialize in producing high-purity physical vapor deposition (PVD) materials with the highest possible density and smallest possible average grain sizes for use in semiconductor, chemical vapor deposition (CVD), and physical vapor deposition (PVD) display and optical applications.


Tungsten Boride Sputtering Target Description

TungstenTungsten is a rare metal found naturally on Earth almost exclusively combined with other elements in chemical compounds rather than alone. It was identified as a new element in 1781 and first isolated as a metal in 1783. Its important ores include wolframite and scheelite.

Tungsten has the highest melting point of all the elements discovered, melting at 3422 °C. It also has the highest boiling point, at 5930 °C. Its density is 19.25 times that of water, comparable to that of uranium and gold, and much higher (about 1.7 times) than that of lead. Polycrystalline tungsten is an intrinsically brittle and hard material (under standard conditions, when uncombined), making it difficult to work. However, pure single-crystalline tungsten is more ductile and can be cut with a hard-steel hacksaw.

Tungsten Boride Sputtering Target Applications

  1. Hard Coatings: WB sputtering targets are primarily used for depositing hard coatings on cutting tools, drill bits, and wear-resistant components in industries like metalworking and machining. These coatings significantly improve the durability and performance of tools by enhancing hardness and wear resistance.
  2. Aerospace and Defense: WB thin films are crucial for aerospace and defense applications. They are used to protect critical components in aircraft and rocket engines, such as turbine blades and nozzles, from high temperatures and extreme conditions. This ensures the reliability and longevity of these components in demanding environments.
  3. Electronics: In the electronics industry, WB is employed in semiconductor manufacturing. It is used to create thin-film resistors and integrated circuits (ICs) due to its unique electrical properties. WB thin films can be deposited on substrates to produce electronic components, contributing to the miniaturization and performance improvement of electronic devices.
  4. Optical Coatings: Tungsten boride coatings play a vital role in optics. They are applied to optical lenses, mirrors, and other components to enhance their durability and performance. These coatings improve reflectivity, reduce glare, and extend the lifespan of optical elements, making them essential in optical systems and devices.
  5. Energy Storage: WB is increasingly explored for applications in advanced energy storage systems, including lithium-ion batteries and supercapacitors. Its excellent thermal stability and electrical conductivity properties make it a promising candidate for improving the energy storage and conversion capabilities of these technologies, which is crucial for the growing renewable energy sector and electric vehicles.
