“…For the MgAl 2 O 4 spinel, it is known that several factors, such as stoichiometry, cation disorder structures, impurities, mechanical treatment and sintering atmosphere, lead to the formation of a wide variety of complicated point defects [57][58][59][60][61]. Since there is a possibility that the large number of defects serve as trapping centers, it difficult to explain the signals with ESR data.…”

“…MgAl 2 O 4 (spinel) is considered as a commercially important ceramic material because of its moderate thermal conductivity (48 W/m • C), low coefficient of thermal expansion (7.6 × 10 −6 / • C), good thermal shock resistance, high electric resistivity (10 10 cm), chemical inertness or less reactive tendency in oxidizing and reducing atmospheres and high temperature strength [1]. MgO is another high temperature ceramic material bearing similar properties [2,3].…”

“…A medida que aumenta la temperatura, el campo de estabilidad del Al(l) se desplaza hacia valores mayores de P Al . A su vez, el campo de estabilidad del MgO·Al 2 O 3 evoluciona hacia valores mayores de P Al y P CO , lo que pone en evidencia que a medida que aumenta la temperatura, son necesarias mayores cantidades de Al(g) y CO(g) en la fase gaseosa para que la espinela se forme y sea estable (19,20).…”
