Zirconium Diboride (ZrB2) Ultra-High Temperature Ceramic Parts

Pushing the Limits: 2500°C Vacuum Operations

In aerospace thermal protection and extreme vacuum furnace applications, standard technical ceramics fail to maintain structural integrity. This requires the deployment of Ultra-High Temperature Ceramics (UHTCs). Telite Ceramics specializes in the fabrication of custom ZrB2 ceramic parts, engineered specifically to operate in vacuum or inert gas environments at temperatures reaching 2500°C.

1. The Premier Molten Metal Solution

Processing reactive or highly corrosive molten metals demands a container with exceptional chemical stability. A custom Zirconium Diboride crucible offers superior resistance against metallic slags and melts. With a melting point of 3246°C, it provides a robust defense against thermal shock and high-temperature corrosion, ensuring the purity of the melted alloys during complex metallurgical processes.

2. Precision Machining for Extreme Hardness

Zirconium Diboride is renowned for its extreme hardness, making it notoriously difficult to machine. However, Telite Ceramics possesses the advanced tooling and CNC capabilities required to process these materials. Whether you require a tightly toleranced ZrB2 plate for a high-temperature substrate, or complex rings and tubes, we ensure exact dimensional accuracy.

3. Electrical and Thermal Conductivity

Unlike many traditional insulating ceramics, ZrB2 exhibits excellent electrical and thermal conductivity. This dual property makes our UHTC ceramic components highly valuable for specialized electrodes, heating elements, and advanced thermal management systems in extreme environments.
