CERACONDUCT - functional coating for stable high voltage in vacuum

CeraConduct is a ceramic functional coating for the targeted dissipation of surface charges on ceramics under high voltage in vacuum. Through the controlled reduction of electron avalanches (SEE effect: secondary electron emission coefficient 1:10 for Al₂O₃), charge clusters, and arcing, CeraConduct significantly increases electrical stability and operational reliability. The insulating properties of the ceramic are fully retained. The result is durable components and reliable operation even under extreme conditions.
