Magnesium gallate (MgGa₂O₄) has attracted much attention recently in both optical and electrical applications due to its unique and versatile properties.

Compared to many other transparent oxide semiconductors, which suffer from low stability at high temperatures, MgGa₂O₄ has a melting point of about 1,930°C, which makes it easier to process.¹ MgGa₂O₄ also exhibits a large degree of inversion in its crystal structure, unlike other materials in the spinel family, which makes it a perfect host for transition metal cation dopant spectroscopy.
