Matsubayashi Lab
Machine-translated · View original
A new-materials lab working on making hard, brittle ceramics deform.
AboutAbout the lab
Beyond "hard and brittle"
The Matsubayashi Lab studies the phenomenon of plastic deformation in ceramics and its engineering applications.
Ceramics excel in heat resistance and electrical insulation, but the view that they are hard and brittle has long limited their applications.
The central topic is aerosol deposition, a method in which fine particles are shot at a substrate at high speed to form a dense thick film at room temperature.
Using its own single-crystal growth techniques as well, the lab combines experiment and theory to expand what can be done with ceramics.
Key terms
- Plastic deformation
- A change in shape that does not return to the original shape even after the applied force is removed
- Aerosol deposition (AD) method
- A method in which ceramic powder is carried in a gas flow and sprayed to form a film at room temperature
- Single crystal
- A crystal in which the atomic arrangement is aligned as one throughout. It is less affected by grain boundaries and defects
NewsLab news
Information on lab assignment has been published (for undergraduates from FY2026, and for graduate students from April 2027 admission)
Associate Professor Matsubayashi joined the university, and the Matsubayashi Lab was launched
ResearchResearch themes
Ceramics are generally said to be hard and brittle, but depending on the material, and in tests at very small sizes, they deform plastically like metals even at room temperature. The lab searches for materials that deform plastically and works on developing new materials and processes that apply this.

For some materials, and in tests at very small sizes, ceramics deform plastically like metals even at room temperature. The lab searches for materials that deform plastically and works on developing new materials and processes that apply the plastic deformation of ceramics.
*Illustrative imageAerosol Deposition (AD) Method
This is a coating method in which powder is sprayed so that ceramic particles deform plastically at room temperature to form a film. The method was developed at the National Institute of Advanced Industrial Science and Technology (AIST), and the lab works on elucidating the film-formation mechanism, the basic properties of AD films, and the development of new materials using AD.
*Illustrative imageCrystal Growth
The lab grows crystals by methods such as vapor-phase growth, flux growth, and hydrothermal synthesis. It is labor-intensive, but it is indispensable for clarifying basic properties without the effects of defects and grain boundaries.
