Cerium Hexaboride (CeB6) Disc, Plate & Sheet

High-Purity Cerium Hexaboride Plate for Electron Systems

In high-end electron microscopy, electron gun systems, and physical vapor deposition, the stability of the source material is important. By using a high-purity Cerium Hexaboride plate, engineers can make use of its thermionic emission characteristics, including relatively low work function and good resistance to carbon contamination.

1. High Density and Purity for UHV

The performance of any thermionic cathode heavily relies on its internal microstructure. Telite Ceramics uses suitable manufacturing routes to produce hot-pressed CeB6 materials with dense structure, uniform grain distribution, and relatively low porosity. Whether you are using a standard part or a customized CeB6 disc, our materials can be considered for stable operation in Ultra-High Vacuum (UHV) environments.

2. Versatility in Sputtering Applications

Beyond electron guns, this material is also used in advanced thin-film deposition. Its electrical conductivity and high melting point make it suitable as a CeB6 sputtering target. Dense and uniform microstructure helps improve erosion consistency during sputtering, which is important for research coating work, specialized semiconductor processes, and optical thin-film development.

3. Precision CNC Machining & Anti-Chipping

This material is extremely hard and brittle, making it difficult to machine without edge chipping. Telite Ceramics employs specialized CNC milling and wire-cutting techniques designed for advanced ceramics. Whether you require a thin CeB6 ceramic sheet, a precision CeB6 disc, or a Cerium Hexaboride plate with countersinks and blind holes, we focus on dimensional accuracy and clean, non-shedding edges.

For drawing-based orders, customers usually confirm part thickness, outer dimensions, hole details, chamfers, and intended application in advance. It is also helpful to confirm flatness, edge distance, and mating structure when the part will be used as an emission component, custom machined part, or CeB6 sputtering target. This helps us recommend a more suitable machining route for a Cerium Hexaboride plate, CeB6 ceramic sheet, CeB6 disc, or hot-pressed CeB6 component.
