Get PriceEffect of magnesia on strength of hydratable alumina
The mechanism of bonding facilitated by the presence of magnesite in hydratable alumina-bonded castables after drying is discussed. The contribution of polycondensation process occurring after dehydroxylation of the hydrates in the castables after firing at 816∘C is proposed as the principal mechanism for strength development.
