Jan 01 2011 · Alumina–magnesia refractory castables are commonly bonded with calcium aluminate cements. At temperatures above 1200 °C these materials present an expansive behavior due to the in situ spinel (MgAl 2 O 4) formation and the CA 2 and CA 6 ones. One alternative to control the volumetric stability is by replacing the typical cements used (30 wt. CaO) for another containing less lime (20 wt
