Large-diameter, high-purity ceramic ring, needed in the development of a next-generation energy source
The world has high hopes for nuclear fusion reactors. Differing entirely from nuclear fission reactors, fusion reactors promise safe and clean power supplies. Kyocera ceramic components are actively used in research of this future energy source.

Working with the Japan Atomic Energy Agency (an independent administrative agency), Kyocera has made a trial version of a large-scale insulator using the world's largest-diameter, high-purity ceramic ring. This component is needed in a neutral beam injector (NBI). The NBI is used to heat plasma and cause a fusion reaction in the International Thermonuclear Experiment Reactor (ITER). In high-voltage testing, insulation performance required by the ITER was demonstrated for the first time.

With earlier technology, manufacturing a ceramic ring to the size needed for megavolt insulation was not possible. Establishing manufacturing technology of large-bore ceramic rings for the ITER was thus a longstanding problem. Kyocera and the Japan Atomic Energy Agency undertook joint development of a large-scale ceramic ring shaping method, and succeeded in its completion. This has contributed greatly to the advancement of ITER/NBI development. There are also high expectations for ripple effects of the technology in the semiconductor industry, and theoretical fields such as particle physics and other areas.
