Metallized ceramics and ceramic-metal composite components for X-ray technology

Metal-ceramic components have several decisive advantages over other materials such as plastic or glass. In contrast to plastic composite parts, ceramic-metal composite parts are suitable for ultra-high vacuum (helium leakage rate 10-8 mbar L/s). On request, high-vacuum-compatible joints up to helium leakage rates of 10-11 mbar L/s can also be produced. In contrast to plastics, ceramics are not subject to degradation by X-rays. Compared to glass, aluminum oxide has a higher mechanical stability and higher dielectric strength. This makes our products ideal for use in X-ray technology.

When developing customized solutions, we rely on more than just our many years of experience. The finite element method (FEM) enables us to design components numerically for X-ray technology in advance. The FEM takes into account the special material properties of ceramic materials. The soldering process itself is simulated as a stress (=“composite stresses”) and – if necessary – external stresses such as temperature changes or mechanical loads are applied. Using this specialized FEM, our products are engineered for superior durability and reliability and are able to meet the unique demands placed on them under harsh high-voltage conditions.

We use a coating developed in-house to prevent the accumulation of electrical charges on ceramic surfaces in a vacuum at high voltage.

With our technical know-how, we are able to develop customized solutions for the most complex requirements in X-ray technology.

In our Alumina X-Ray Systems product family, for example, we produce

  • Detectors for digital and conventional X-ray systems in medical technology
  • Components for X-ray scanners in security technology
  • Solutions for photomultiplier tubes, microwave and traveling wave tubes
  • Components for high-frequency applications in broadcasting technology
  • Filament holders for X-ray tubes
