Shibata (Hiroyuki) Lab
Machine-translated · View original
A lab that examines what happens at high-temperature interfaces to make materials production more efficient.
AboutAbout the lab
Looking at high-temperature interfaces to make materials processes more efficient.
The Shibata Lab aims to clarify the mechanisms of reactions at interfaces involved in material separation processes, and the mechanisms by which physical properties emerge.
In the refining, manufacturing, and recycling of materials, solids, liquids, and gases made of various elements proceed while reacting at high temperatures.
Because the thermal conductivity and viscosity of molten silicates and molten metals play a major role in high-temperature refining processes, the lab investigates how these properties arise in relation to the structure of the material.
In addition, the lab directly observes high-temperature reaction fields, aiming to make materials manufacturing processes more efficient and to develop new processes.
Key terms
- Molten silicate
- A liquid formed when oxides built on a framework of silicon and oxygen melt. It is the main component of the slag produced in smelting.
- Refining
- A process that removes impurities from extracted metal and adjusts it to the required composition.
- Thermal conductivity
- A value indicating how readily heat is conducted through a substance. The larger the value, the better heat is conducted.

ResearchResearch themes
To make the processes of refining, manufacturing, and recycling materials more efficient, the lab clarifies how different phases separate at high temperatures. To that end, it investigates the chemical and physical properties of each phase and interface at high temperature, pursuing research under the motto "integrating property research and process research."
*Illustrative imageHeat Transfer in Molten Silicates
The thermal conductivity of molten silicates plays an extremely important role in high-temperature refining processes. The lab investigates how heat is transferred in relation to the structure of the material.
*Illustrative imageViscosity and Structure of Molten Silicates
Viscosity is also a property that governs refining processes, and it sensitively reflects the structure of the material. The lab clarifies how viscosity arises by linking it to the structure of molten silicates.
*Illustrative imageThe Interface between Molten Silicates and Solid Metals
Material separation processes and crystal growth involve reactions at the interface where a liquid and a solid meet. The lab directly observes high-temperature reaction fields to clarify the mechanisms of these reactions.
