Exploring novel ways to make and recycle ceramics+
Many ceramic components are used in the latest electronic equipment, but the process of making them is ridden with difficulties. Therefore, the concerned parties are trying to find easier ways to produce them at low costs. It is also important to develop methods to recover gallium and other rare elements used in electronic components such as white LEDs. Our laboratory is developing new methods to make ceramic materials and recover elements from the finished products by improving the reaction processes and reaction devices.

Materials science and engineering
We are developing new methods to make ceramics for use in white LEDs and next-generation semiconductors and to recycle rare elements, thereby contributing to energy and resource conservation.
- Production of gallium nitride from gallium oxide
- Recovery of gallium from spent white LEDs
- Synthesis of nitride compounds from oxides by using ammoniacal nitrogen
