Lanthanum Hexaboride (LaB6) Tube, Sleeve & Machined Part

Reliable Performance in Extreme Vacuum Environments

In Ultra-High Vacuum (UHV) furnaces and advanced plasma research, the structural integrity of conducting elements is non-negotiable. Utilizing a high-purity LaB6 tube provides an exceptional balance of low work function and high thermal stability. Telite Ceramics addresses the common issues of brittle failure and outgassing by manufacturing fully densified hot-pressed LaB6 components designed for long-term reliability in electron beam assemblies.

1. Hot Pressing for Enhanced Density

Standard sintering often results in residual porosity, which leads to gas trapping and uneven thermal expansion. By employing an advanced vacuum hot-pressing process, our LaB6 ceramic tube achieves near-theoretical density. This porosity-free structure not only prevents contamination in sensitive vacuum environments but also significantly enhances the mechanical strength required for load-bearing Lanthanum Hexaboride sleeve applications.

2. Precision CNC and Concentricity Control

Manufacturing long, thin-walled ceramic components requires specialized tooling to prevent vibration-induced micro-cracks. Whether you require a standard rod or a complex LaB6 machined part, Telite Ceramics applies strict concentricity and runout tolerances down to the micrometer level. Our precision grinding process ensures that internal threads and locating steps fit seamlessly into your vacuum systems without creating installation stress.

3. Applications in Advanced Physics and Electronics

Our LaB6 components are widely utilized in vacuum heating elements, sensor protection, and electron gun cathode supports. The material’s stable electrical properties make it a premier choice for Lanthanum Hexaboride shielding and structural nodes. Each part is finished with precision chamfering to eliminate micro-stresses and prevent chipping during high-temperature thermal cycling.
