Ceramic-to-metal seals (CTMS)
High-performance sealing solutions for demanding applications
Electrovac Components develops and manufactures metal components for ceramic-to-metal seals (CTMS). These are hermetically sealed connections between ceramic materials and metal components.
This technology combines the excellent electrical insulation properties and thermal stability of ceramics with the mechanical strength and connectivity of metal to create reliable sealing solutions for high-performance industrial applications.
This is a ceramic-to-metal seal (CTMS)
A ceramic-to-metal seal (CTMS) is a component in which a ceramic material is joined to a metal part in a gas-tight manner. Ceramics offer excellent electrical insulation, temperature resistance, and chemical resistance, while the metal provides mechanical strength and connectivity.
These pressure-, temperature-, and electricity-resistant connections are used where standard seals reach their limits—for example, in vacuum or high-temperature environments.
Technology for extreme operating conditions
CTMS are manufactured using specialized metallization and brazing processes, in which ceramic insulators are joined to metal parts in a positive-locking and gas-tight manner.
This connection creates a robust, vacuum-tight, and electrically insulated structure that withstands even extreme temperatures, high electrical loads, vacuum conditions, and thermal cycling.
Applications and benefits
Ceramic-to-metal seals are particularly suitable for applications requiring high temperature and voltage resistance, low outgassing, and permanent hermetic sealing—such as in aerospace and vacuum technology, sensor technology, semiconductor manufacturing, or medical technology. The high reliability and durability of CTMS make them the preferred choice in systems where the risk of failure must be minimized.
Comprehensive project support
From the concept phase through design, material selection, and simulation to prototype construction and series production, Electrovac Components provides comprehensive support to its customers for CTMS projects. Integrated testing and quality processes ensure that every ceramic-to-metal connection meets the high requirements of industrial applications.
