采用三触点保护环技术测量了MgAl2O4和Y3Al5O12在1260 K下的单晶和多晶电导率。电导机制随温度变化，在900 ~ 1000 K之间，log σ / T - 1曲线出现异常和随时间变化的拐点。Y3Al5O12和MgAl2O4的传导过程相似，可能与A13+离子扩散有关。
The electrical conductivities of single crystal and polycrystalline MgAl2O4 and Y3Al5O12 were measured to 1260 K using a three-contact, guard-ring technique. The electrical conduction mechanisms change with temperature, with anomalous oxygen pressure and time-dependent inflections in log σ versus T−1 curves between 900 to 1000 K. The conduction processes of Y3Al5O12 and MgAl2O4 appear to be similar and possibly related to A13+ ion diffusion.
