LaB6 Ceramic is an inorganic non- metallic compound composed of low-valence boron and the rare metal element lanthanum. It is a refractory ceramic that could resist high temperature and harsh environments. LaB6 ceramic has lots of applications due to its ideal thermal, chemical, and electronic properties. As LaB6 ceramic has the characteristics of high emission current density and low evaporation rate at high temperature, it always work as a cathode material with superior performance and has radually replaced some tungsten cathodes in industrial applications. Features: 1. Excellent thermal shock resistance 2. Good electrical conductivity 3. Excellent chemical and oxidation resistance 4.High electron emissivities 5.Stable in Vacuum Applications: • Scanning Electron Microscopes • Transmission Electron Microscopes • Electron Micro Probe Analyzers • Electron Lithography Systems • Electron Accelerators • Thermal Cathode
