Molten Materials Physical Chemistry Lab
Machine-translated · View original
A lab that measures the properties of materials melted at high temperatures and makes them visible.
AboutAbout the lab
Creating tomorrow’s “normal” through technology that melts
The Molten Materials Physical Chemistry Lab studies the physicochemical properties of high-temperature melts and develops technologies that make metal refining processes more efficient while reducing their environmental impact at the same time.
The lab is developing new measurement techniques for viscosity, electrical conductivity, wettability, and surface tension, as well as sensing technologies combined with mathematical models.
It also researches technologies for visualizing the “invisible,” such as ultra-high-temperature conditions, and the evaluation of the physical properties of ceramics.
Through an interdisciplinary approach that integrates theory and practice, the lab also sees it as its mission to train people who will lead the next generation of materials science.

*Illustrative imageMeasuring the properties of high-temperature melts
The lab precisely evaluates the physicochemical properties of substances melted at high temperatures, and explores new scientific principles by combining theory and experiment. It clarifies how changes in temperature, composition, and phase affect melts, and builds the foundation for efficient manufacturing processes.
*Illustrative imageInnovating metal refining processes
The lab is rethinking the steps for efficiently extracting high-quality metals from raw materials, and is developing next-generation technologies that reduce environmental impact while achieving both quality and productivity.
*Illustrative imageVisualizing extreme environments
The lab studies technologies that make phenomena invisible to the eye, such as those at ultra-high temperatures, visible. It analyzes the complex flow phenomena of high-temperature melts and proposes methods for process optimization and quality improvement.
*Illustrative imageEvaluating the physical properties of ceramics
The lab explores the potential of ceramics as next-generation materials, not only melts. It designs materials with excellent heat resistance and corrosion resistance, and develops them for applications in extreme environments.
