SAN DIEGO — Feb. 24, 2020 — Kyocera International, Inc. today introduced a new ceramic material, AH100A Alumina, that provides superior high-voltage electrical insulation performance. Its proprietary formulation offers four key advantages:

  • 90 Percent Faster Conditioning Time. Kyocera’s AH100A Alumina can be conditioned to 100 kilovolts (kV) in about 30 minutes, a time savings of approximately 90 percent in comparison with the typical 100kV conditioning time required by conventional alumina.
  • >60 Percent Higher Creeping Voltage Resistance. In Kyocera’s tests, AH100A Alumina has been shown to offer >60 percent better creeping voltage resistance — with ultimate field intensity averaging 14.1 megavolts per meter (MV/m), as compared to 8.4 MV/m for conventional alumina.
  • >20 Percent Higher Breakdown Voltage Resistance. Under measurement tests with 1mm-thick substrates, Kyocera’s AH100A delivered a >20 percent improvement in breakdown voltage resistance — withstanding up to 24 MV/m, as compared to 19 MV/m achieved by conventional alumina.
  • Unprecedented Potential for Miniaturization and Lightweighting. Due to its superior insulation performance, Kyocera’s AH100A Alumina brings unique opportunities for miniaturization and weight savings. Designers can expect equivalent electrical insulation with 50 percent less external volume, significantly lower mass, and lighter weight.

These characteristics give Kyocera’s AH100A Alumina outstanding benefits — applications include scientific instruments, such as mass spectrometers, SEM and TEM microscopes; X-ray, CT and MRI systems; particle accelerators; electron beam positioning; and many other types of high-voltage equipment or components involving power between 5kV and 1MV.

Kyocera’s advanced ceramics are known as the “superheroes of advanced technology” due to their unique electrical, physical, chemical, optical and thermal properties. As a world leader in the field, Kyocera offers advanced ceramics in approximately 200 different formulations — including Aluminum Oxide, Aluminum Nitride, Cermet, Cordierite, Forsterite, Mullite, Sapphire, Silicon Carbide, Silicon Nitride, Steatite, Yttria and Zirconia. The company has developed a wide range of proprietary process technologies that can incorporate dry-pressing, cold-isostatic pressing, hot-isostatic pressing, injection molding, tape casting, multilayering and/or metallizing ceramics, to help clients overcome extreme technical challenges.

About Kyocera

Kyocera International, Inc., founded in 1969 and headquartered in San Diego, California, is a wholly-owned subsidiary of Kyoto, Japan-based Kyocera Corporation.

Kyocera Corporation (TOKYO:6971) (, the parent and global headquarters of the Kyocera Group, was founded in 1959 as a producer of fine ceramics (also known as “advanced ceramics”). By combining these engineered materials with metals and integrating them with other technologies, Kyocera has become a leading supplier of industrial and automotive components, semiconductor packages, electronic devices, solar power generating systems, printers, copiers and mobile phones. During the year ended March 31, 2019, the company’s consolidated sales revenue totaled 1.62 trillion yen (approx. USD14.6 billion). Kyocera appears on the “Derwent Top 100 Global Innovators 2018-19” list by Clarivate Analytics and is ranked #655 on Forbes magazine’s 2019 “Global 2000” list of the World’s Largest Public Companies.
