Melting temperature of al2o3
WebChemical Engineering & Technology, 35 (2012), 3, 455-463 2012. Abstract. In the last years, a lot of ceramic materials were developed that, at higher temperatures, have a high electrical conductivity and a high conductivity of oxygen ions. Such mixed ionic/electronic conductors can be used to produce high-purity oxygen.
