Lanthanum borite (LaB6) ion source for thin film coating

  Wuxi Tecceram Fine Ceramic Co., Ltd, founded in 2013, is focus on high technique and high precision engineering ceramic products. Material for coating include high purity Lanthanum Borite (>99.9%, LaB₆), alumina (>99.8%, ivory color) and Boron Nitride (BN). The raw material of these ceramics are imported from Janpan and France.

  Lanthanum borite (LaB₆) is a popular material used as a cathode in electron beam evaporation sources for thin film coating applications. It is known for its high thermionic emission and low work function, making it an efficient source of electrons for coating processes.
  The lanthanum borite Ion Source typically consists of a crucible or filament made of LaB₆ material. When heated, the LaB₆ material emits a large number of electrons due to its low work function. These electrons are accelerated and focused onto a target substrate, where they deposit as a thin film coating.

  The advantages of using a lanthanum borite ion source for coating include:
  1. High thermionic emission: Lanthanum borite has a high thermionic emission, meaning it can emit a large number of electrons when heated. This leads to a high deposition rate and efficient coating process.
  2. Low work function: Lanthanum borite has a low work function, which means it requires less energy to remove electrons from its surface. This results in a lower power consumption and longer filament lifetime.
  3. Stability and durability: Lanthanum borite is a stable material that can withstand high temperatures and harsh environments. It has a long lifespan and can be used for extended coating processes without degradation.

  4. Wide range of applications: Lanthanum borite ion sources are used in various coating applications, including optical coatings, semiconductor device fabrication, and surface modification.
  In summary, a lanthanum borite ion source is a reliable and efficient option for coating processes due to its high thermionic emission, low work function, stability, and durability.
