Corundum Refractory Material in Alumina-Binder Resistant to High-Temperature Deformation

Corundum Refractory Material in Alumina-Binder Resistant to High-Temperature Deformation

In order to provide a good resistance for refractory structures towards high-temperature deformation during manufacture of engineering ceramic during firing at 1650°C a corundum refractory material is developed with a weight faction of more than 95 wt.% Al 2 O 3 . The ceramic binder used is high-tem...

Zusammenfassung:In order to provide a good resistance for refractory structures towards high-temperature deformation during manufacture of engineering ceramic during firing at 1650°C a corundum refractory material is developed with a weight faction of more than 95 wt.% Al 2 O 3 . The ceramic binder used is high-temperature calcium hexa-aluminate formed during firing molded objects from a thixotropic mixture consisting of refractory filler of electromelted corundum and components for forming a binder, i.e., high-alumina cement (HAC) and finely ground alumina.
