The international technology group SCHOTT has expanded its range of dielectric materials to include the POWERAMIC® N150 glass-ceramic. POWERAMIC® comprises a family of highly homogeneous and pore-free glass-ceramics for use as dielectrics. These products enable extremely high dielectric breakdown strength compared to other materials.
The energy storage density of POWERAMIC® exceeds that of current capacitor solutions by a factor of up to ten. In high-voltage applications, their excellent dielectric properties allow for significantly smaller, lighter weight passive components, such as capacitors, even at high temperatures.
The advantages of the new POWERAMIC® N150 glass-ceramic include a particularly high constancy of the dielectric properties compared to conventional ceramics, e.g. very low dependence of storage capacity and loss over a significantly broader temperature and frequency range. This opens up potential, especially in pulsed operations with short pulse durations and steep pulse slopes. By that, a variety of new applications in the high-voltage sector, such as transducers in high-voltage networks, but also test, filter and resonant circuit capacitors can be addressed.
“POWERAMIC® N150 glass-ceramic is a highly stable dielectric that builds on the existing material advantages of the POWERAMIC® family and is well-suited for use in applications that involve extremely high frequencies,” explains Dr. Martin Letz, Senior Principal Scientist at SCHOTT Research & Technology Development. “There are ceramics that have similar material properties on the market. Nevertheless, the more compact designs that new application areas require can only be produced by using glass-ceramics due to their high dielectric breakdown strength.”
The POWERAMIC® material family from SCHOTT is RoHS-compliant and free of lead and halogens.
