We have synthesized spinon thermal conductivity materials in Sr – Cu – O system by glass‐ceramics technique. The materials are promising for active control of thermal energy in microelectronic devices because of high and anisotropic thermal conduction, its controllability, and electric insulation. Nevertheless, research on these materials has been limited to that concerning theoretical perspectives and investigation of physical properties using large single crystals. In this study, we adopt glass‐ceramics technique to synthesize these materials: We prepared melt‐quenched multicomponent oxides including SrO and CuO , and checked its glass‐forming ability and crystallization behaviors by heating. As a result, we have found that SrCuO 2 and Sr 14 Cu 24 O 41 , known as the spinon thermal conductivity materials, are synthesized using SrO – CuO –‒ Li 2 O –‒ Al 2 O 3 ‒– Ga 2 O 3 system. This synthesis process for the system will provide practical application of the spinon thermal conductivity materials.
