BEST VALUES FOR NEW ENERGIES AND E-MOBILITY

Very high flexural strength, good thermal conductivity, excellent electrical insulation and top values for dielectric strength: all this is offered by the new high-performance substrate Rubalit^® ZTA, which ceramics specialist CeramTec is presenting at PCIM in Nuremberg. ZTA stands for Zirconia Toughened Alumina - and for a material that is also predestined for high-performance applications such as electromobility and power generation due to the properties mentioned.

With Rubalit^® ZTA and another high-tech substrate announced for this year, CeramTec is expanding its substrate portfolio to include solutions specifically tailored for use in highly electrified industries and e-mobility. The power electronic modules in this environment must meet increasingly stringent requirements in terms of their temperature resistance and miniaturization. With these key specifications in mind, CeramTec has developed a substrate with impressive properties.

Compared to the widely used aluminum oxide as a substrate material, the flexural strength has been improved by 40 percent to more than 625 MPa. In practice, this means a significantly higher fatigue strength of power modules built on Rubalit^® ZTA. Thermal conductivity is more than 26 W/mK, and in dielectric strength the new substrate reaches 25 kV/mm. This makes Rubalit^® ZTA clearly superior to common PCB materials, for example. Its thermal conductivity, temperature resistance and insulating properties also make the substrate an ideal material for use in passive components or chip resistors.
