Attempt to fabricate a high thermal conductivity, transparent oxide glass by dispersing MgO crystals and refractive index matching

Oxide glasses generally have low thermal conductivity due to their disordered structures. Here, a fabrication method to provide them with high thermal conductivity while retaining their optical transparency is proposed. It consists of dispersing ∼20 μm MgO crystals in a glass matrix and matching the...
