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 lanth…
