The lab creates advanced ceramics by controlling powder processes scientifically.

AboutAbout the lab
Creating advanced ceramics from powder
The Advanced Ceramics Lab aims to create advanced ceramics and composite materials that contribute to the environment, energy, and information devices.
The lab studies how to elucidate and control powder processes, including particle synthesis, dispersion, forming, sintering, and machining, in a more scientific way rather than relying on intuition and experience.
It holds that establishing methods of making materials while improving mechanical reliability, that is, making components harder to fracture, is essential.
On the lab's website, it is introduced under the name "Tatami-Iijima Lab."
Key terms
- Powder process
- A method of making ceramics and composite materials through steps such as particle synthesis, dispersion, forming, sintering, and machining
- Optical coherence tomography
- A technique that uses light to observe the inside of a material in three dimensions. This lab uses it to observe the process by which ceramics form
- Master sintering curve
- A theoretical method for analyzing how materials shrink during sintering
- Composite particles
- Particles made by mechanically applying compressive shear force to particles of different sizes

ResearchResearch themes
Centered on powder processing technology, the lab aims to create ceramics and composite materials whose structures are controlled from the atomic to the nano to the micro scale. It studies the whole process of making materials from powder, including observing how structures form, designing and compositing particle surfaces, and evaluating the fracture properties of materials.
*Illustrative imageObserving and Optimizing the Manufacturing Process in 3D
Using optical coherence tomography, the lab observes the internal structure of ceramics in three dimensions, in real time, as they form. By elucidating the factors behind structure formation through approaches such as designing particle interfaces, it aims to optimize the entire manufacturing process.
*Illustrative imagePowder Processes for High Functionality and High Reliability
By combining powder processing and analysis equipment such as bead mills, spray dryers, and atmosphere-controlled pressure sintering furnaces, the lab works to make ceramics more functional and more reliable. It also conducts theoretical research, such as analysis of sintering shrinkage using master sintering curves.
*Illustrative imageControlling Ceramic Structure with Composite Particles
Applying mechanical compressive shear force to particles of different sizes to make composite particles makes fine particles easier to handle and allows them to be dispersed uniformly. This works regardless of particle type, making it possible to control the microstructure of ceramics and improve their properties.
*Illustrative imageSurface Modification to Disperse Nanoparticles
For functional nanoparticles a few to several tens of nanometers in size, preventing aggregation and stabilizing dispersion is the key to controlling and improving their function. The lab works on techniques to disperse them uniformly in organic solvents and resins using functional anionic surfactants and multistep surface modification.
