We aim to give high thermal conductivity to glass, which is known as a material that does not conduct heat well, and to apply it to new fields.

If mixed with a high thermal conductive material, glass can be a good conductor of heat. However, all the advantages of glass, such as transparency and freedom of molding, are lost. In this research, we succeeded in developing a transparent glass with high thermal conductivity that retains its glassiness by adopting the strategies of high thermal conductivity MgO deposition and refractive index matching.
