Abstract

The creep properties of a standard doloma brick (containing ∼ 40% MgO) and a magnesia-enriched doloma product (containing ∼ 60% MgO) have been compared with the behaviour of CaO-MgO samples having compositions and microstructures similar to those of the pellet raw materials used for manufacture of the fired doloma refractories. The creep strength is shown to be improved not only by magnesia enrichment but also by reducing the impurity levels, particularly the Fe2O3 content.
