Monolithic refractories. "Monolithic refractories" is a general term for refractories of granular material and clay type. There are castable refractory materials, gunning materials, patching materials, and others which can be used in various ways depending on the particular purpose. Gunning materials are mainly used to make repairs.

The hydration resistance of a low-flux CaO . MgO refractory is increased by incorporating at least 0.01 percent by weight of a stabilizing agent selected from the group consisting of Al2O3, V2O5, aluminum fluoride, MgF2, and CaF2, and mixtures thereof to increase the total content of the stabilizing agent in the refractory grain to from 0.01 percent to about 1.0 percent by weight.

Dolomite brick is the most important stable refractory under the working conditions of Argon Oxygen De-carbonization (AOD). For AOD applications, the Dolomite bricks should have positive Permanent Linear Change (PLC) on re-heating. A positive PLC dolomite brick has higher life and most suitable for joint less refractory lining with no cobble stoning defect.

Dead burnt refractory dolomite is produced in rotary kilns. Generally high-grade dolomite, containing combined impurities less than 3%, is selected for dead burning. As it is difficult to densify high purity dolomite in a rotary kiln, it is customary to use some mineralizers to facilitate dead burning. Iron oxide is a common additive.
