The lab creates ceramics that withstand the harsh environments of space and nuclear reactors.

AboutAbout the lab
Developing advanced ceramics that withstand harsh environments
The Yoshida Lab develops advanced ceramic materials intended for use in harsh environments.
By controlling microstructure at the nano, micro, and macro levels, the lab improves reliability and gives materials new properties and functions.
The intended applications are in aerospace, nuclear power and fusion, and energy and environment fields.
The lab also works on engineering ceramics and their process development with an eye to carbon neutrality, low environmental impact, energy saving, and resource saving.
Key terms
- Ceramics
- Inorganic materials made by firing and hardening, neither metal nor resin. They resist heat well but break easily
- Ceramic matrix composites
- Materials that combine ceramics with ceramic fibers to make them harder to crack
- Microstructure
- The arrangement of grains, fibers, and gaps inside a material at a scale visible under a microscope

ResearchResearch themes
The lab studies how to improve the reliability of ceramics and give them new properties and functions by controlling their microstructure. It aims for use in harsh environments such as aerospace, nuclear power and fusion, and energy and environment fields.
*Illustrative imageCeramic matrix composites
Ceramics are brittle, which raises concerns about their reliability as structural components. The lab therefore develops new fabrication processes for fiber-reinforced ceramic matrix composites, which combine ceramics with ceramic fibers, evaluates their properties, and works on giving them functions through distinctive structures.
*Illustrative imageCarbon neutrality and advanced ceramics
The lab develops highly reliable heat-resistant materials for aerospace and for next-generation nuclear power and fusion reactors, as well as heat-control materials, low-friction and wear-resistant materials, and plasma-resistant materials for semiconductor manufacturing equipment. It is also pioneering green processes for ceramics.
*Illustrative imageCeramics that withstand harsh environments
The lab clarifies how the properties and microstructure of materials change when they are exposed to high temperatures, steep thermal gradients, corrosive and oxidizing atmospheres, and radiation and particle beam irradiation. Based on the results, it develops materials that withstand harsh environments, such as accident-tolerant fuel and control materials for fast reactors.
