Lanthanum Hexaboride (LaB6) Disc, Plate & Machined Part

Material Characteristics and Machining Standards

In vacuum electron emission and advanced physics laboratory equipment, achieving a stable electron source is critical. Due to its low work function (~2.66 eV) and excellent high-temperature properties, a reliable Lanthanum Hexaboride plate is widely utilized as a cathode material for thermionic emission. Telite Ceramics guarantees exceptional material density and strict dimensional controls to satisfy the rigorous technical requirements of electron beam systems.

1. Hot Pressing Material Process

The microstructure of the ceramic directly influences its high-temperature performance. Telite Ceramics utilizes an advanced vacuum hot-pressing technique to eliminate internal porosity. This dense hot-pressed LaB6 ensures structural integrity and extends the operational lifespan of the cathode assembly by preventing outgassing in high-vacuum environments.

2. Strict CNC Tolerances and Micro-Machining

Because LaB6 exhibits extreme hardness coupled with brittle characteristics, specialized processing is mandatory to prevent edge chipping. Whether you need a standard LaB6 disc or a highly complex LaB6 machined part with precise countersinks and through-holes, we apply strict dimensional controls. Our double-sided grinding achieves micrometer-level precision for flatness, while our specific edge chamfering relieves machining stress to eliminate clamping fracture risks.

3. Custom Configurations for Advanced Equipment

We provide tailored solutions adapted to your specific vacuum electronic platforms. From robust structural blocks to a delicate, ultra-thin LaB6 ceramic sheet, our components serve as reliable conductive elements and high-temperature structural nodes.
