Tohoku University Technology: Metal / ceramic composite material: T16-100
Possible to produce high laser absorption metal powder with finely dispersed ceramic on the surface, and metal/ceramic composite material having complex shape!
Metal and ceramic repel each other when mixing due to their positive surface charge. So since they are dispersed away, the composite can not be formed. The conventional technology uses a binder composed mainly of polyvinyl alcohol to glue metal and ceramic. This is then sintered in order to make a composite powder. However, the binder reduces the functionality due to compositional change (specifically, mechanical property deterioration, optical absorbance decrease, etc.) and handling during production is difficult. This invention is able to easily make ceramic / metal composite by using carbon nanotube (CNT). Application of various powder to bulk material is expected, such as sintered material and composite material by 3D printer. It is also possible to create a pure composite of metal / CNT, and this technology is expected to improve the antioxidation property of the base metal material.

Company information
The revenue generated from technology transfer is reinvested as new research funding for universities and researchers, and is utilized to create further research outcomes. To ensure the smooth operation of this cycle, known as the "Intellectual Creation Cycle," we will vigorously promote technology transfer. The types of seeds we handle include patents, know-how, databases, and programs. We have established a collaborative framework by signing basic technology transfer agreements with the following universities (as of June 1, 2025): Tohoku University, Hirosaki University, Iwate University, Akita University, Fukushima University, Yamagata University, Tohoku Gakuin University, Iwate Medical University, Fukushima Medical University, Aizu University, Miyagi University, Hokkaido University, Muroran Institute of Technology, and Showa Medical University.
