Lanthanum Hexaboride Rod/Bar Description
Lanthanum Hexaboride Rod/Bar is a highly stable, conductive ceramic material engineered for demanding electron emission applications. With its low work function (~2.4 eV), high melting point (~2528°C), and exceptional resistance to chemical corrosion, LaB6 enables efficient thermionic electron emission at relatively low temperatures. This makes it a preferred cathode material in a wide range of high-tech systems. It is commonly used in RF ion sources, mass spectrometers, Hall thrusters, plasma generators, and micro-mirror devices, where precision, longevity, and thermal stability are critical. In addition to its excellent emission characteristics, LaB6 rods/bars offer consistent performance under vacuum and high-temperature environments, with minimal evaporation or degradation over time.

Lanthanum Hexaboride Ceramic Properties
Lanthanum Hexaboride Ceramic Material Machining
Lanthanum Hexaboride (LaB6) Ceramic is a specialized material prized for its excellent thermionic emission, high melting point, and chemical stability. These properties make it essential in electron emission applications but also pose challenges in machining due to its hardness and brittleness. Key machining considerations include:
- Cutting: Precision diamond-coated tools or laser cutting methods are necessary to achieve clean edges while preventing microcracks and surface damage.
- Grinding: Fine diamond grinding wheels provide the accuracy needed to maintain dimensional tolerances and surface smoothness, particularly for intricate or small components.
- Drilling: Ultrasonic or abrasive waterjet machining techniques are often used to create precise holes and features without inducing thermal stress or cracking.
- Surface Finishing: Polishing processes improve surface quality, reduce electron scattering, and enhance emission efficiency, which is critical for high-performance cathode applications.
Lanthanum Hexaboride Ceramic Packaging
Lanthanum hexaboride ceramic products are typically packaged in vacuum-sealed bags to prevent moisture or contamination and wrapped with foam to cushion vibrations and impacts during transport, ensuring the quality of products in their original condition.
