Structural characteristics of MgAl2O4 spinel [PDF]

open access: yes, 2023
Magnesium aluminate spinel (MgAl2O4) is a material with good mechanical, chemical, and thermal properties, low dielectric permeability and loss tangent. Based on those properties, MgAl2O4 has found a significant application in refractory ceramics, ceramics windows, integrated electronic devices, etc.
