FRIALIT®-DEGUSSIT® Technical Ceramics
Electrical Feedthroughs, Insulating Tubes and brazed ceramic-to-metal components
With around 150 years experience in the manufacture of ceramics for demanding applications, Friatec have been manufacturing FRIALIT brazed ceramic-to-metal assemblies for almost 50 years and in that time have gained unparalleled experience in the field. Working closely with customers, for every application's requirements, our experts develop the optimum solution based on high-performance materials.
Technically advanced applications place exceptional demands on the material used: demands that often push metal, glass and plastics to their limits. This is when FRIALIT-DEGUSSIT oxide ceramics come to the fore. They are extremely resistant to heat, corrosion and chemical influences, whilst fully retaining shape and wear-resistance. Our high-performance ceramic components retain full functionality, regardless of the demands placed upon them.
Our ceramic-to-metal components are widely used, especially in the highly-demanding fields of electrical and medical technology and are vital components for accelerators and particle sources. Renowned institutes throughout the world rely on our high-performance materials. Special ceramic components with individual design and state-of-the-art technology are the answer to the problems of researchers and developers.
From high-vacuum and pressure resistant electrical feedthroughs and insulating tubes, produced in series or custom- designed and manufactured according to specific application requirements, the application fields have developed and now include:
The X-ray tube lies at the very heart of computerised tomography. It enables doctors to reach a precise diagnosis while keeping patient radiation exposure to a minimum.
The key components indispensable for modern X-ray diagnostics are the X-ray tube and X-ray image intensifier – components made of FRIALIT- DEGUSSIT Oxide Ceramics.
Our oxide ceramic products are the result of decades of experience combined with intensive research and development and customer-focused product implementation. The X-ray image intensifier made by FRIATEC is an outstanding example of successful and sustainable cooperation with our customers. Tried and tested over many years, the product has been well-proven in practice and is now used in the field of radiology throughout the world.
The Heidelberg Ion-Beam Therapy Centre (HIT), designed as the first German institute for clinical radiation therapy, and currently the only therapy unit for heavy ions in Europe, rely on our oxide ceramics.
Kicker chambers made of FRIALITDEGUSSIT Oxide Ceramics are fundamental components of the accelerator. They ensure optimum therapeutic results while at the same time minimizing the radiation dose for the patient
Vacuum chambers made of FRIALIT-DEGUSSIT Oxide Ceramics are used in accelerator units. In fast-pulsed bending magnets they also serve the purpose of injecting and extracting particles.
Demands on components made of oxide ceramics are extremely high during operation. High mechanical strength and loading capacity ensure reliability during operation. Components made of ceramic-to-metal compounds boast numerous exceptional properties: They provide maximum electrical insulation, remain fully tight under extreme pressure or vacuum conditions, are exceptionally corrosion-resistant and even withstand temperatures exceeding 350 °C.
In contrast to metallic parts, ceramic components avoid the shielding of the rapidly changing external magnetic fields. Ceramic material is not heated by eddy currents. The additional coating on the inner surfaces of the ceramic chambers, e.g. Ti or TiN, ensures the reliable discharge of image current and prevents secondary electron emission.
In close cooperation with scientists, FRIATEC develops customized solutions of the highest technological standard. For this purpose FRIATEC carefully selects the best ceramic-to-metal compound for each application. A wide variety of compounds can be implemented either by traditional methods using metalized ceramics or by active welding.
A wide variety of magnetic and nonmagnetic metals are here available. Due to their exceptional properties and the individual approaches offered, accelerator units made of FRIALIT-DEGUSSIT Oxide Ceramics are the products of choice in renowned German institutes. These include the German Electron-Synchrotron Foundation (DESY) based in Hamburg and Zeuthen, the Jülich Research Centre (FZJ), the Helmholtz Centre for Heavy-Ion Research (GSI) in Darmstadt and the Karlsruhe Institute of Technology (KIT).
Also at international level many institutes rely on accelerator units made of FRIALIT-DEGUSSIT Oxide Ceramics: the Large Hadron Collider (LHC) at CERN, the European Organization for Nuclear Research in Switzerland, Cornell University, Ithaca, USA, and the Budker Institute of Nuclear Physics (BINP) at Nowosibirsk in Russia.
The ultra-high vacuum places new demands on conventional materials and joining techniques. Components made of FRIALIT-DEGUSSIT Oxide Ceramics are able to fully meet these challenges and show their strengths in the vacuum.
Minimum outgassing and leakage rates combined with optimum electrical insulation and thermal resistance guarantee an excellent level of reliability. Electrical feedthroughs made of ceramic-to-metal components allow transmission of the smallest measurement signals between the vacuum chamber and the outside. Insulation tubes provide reliable separation of areas with different potentials. With crucibles made of FRIALIT-DEGUSSIT Oxide Ceramics materials can be reliably evaporated in the vacuum. Capillaries, tubes and insulating beads ensure perfect electrical insulation in vacuum chambers. Focusing units in electron microscopes require tolerances of just a few μm. Only this enables the most varied products from research and technology to be examined at maximum resolution and depth of field. The lowest leakage and desorption rates are decisive for the functionality of the microscope.
Due to their shape stability and outstanding electrical insulation properties, components made of FRIALIT-DEGUSSIT Oxide Ceramics guarantee excellent measurement results.
