Today, majority of the magnesia refractories contain sintered and / or fused grain, both being a synthetic product. Magnesia-carbon (MgO-C) refractory is important and widely used refractory in the steelmaking. It is characterized by a reduced slag infiltration depth and a high thermal shock resistance due to its carbon (C) content.

11.5.1 Process Description1-2. Refractories are materials that provide linings for high-temperature furnaces and other processing units. Refractories must be able to withstand physical wear, high temperatures (above 538°C [1000°F]), and corrosion by chemical agents. There are two general classifications of refractories, clay and nonclay.

Refractory bricks in a torpedo car used for hauling molten iron. A fire brick, firebrick, fireclay brick, or refractory brick is a block of ceramic material used in lining furnaces, kilns, fireboxes, and fireplaces.A refractory brick is built primarily to withstand high temperature, but will also usually have a low thermal conductivity for greater energy efficiency.
The possibility of using crushed spent magnesia refractories as new refractory ceramic masses is also mentioned in other works [16], [21]. Due to the magnesite belongs to a group of critical raw materials, spent MgO and MgO-C refractories could be a valuable source of magnesium oxide for the production of basic refractories.
The rate of heat flow in refractory constructions can be calculated only approximately for several reasons. Other important factors which affect the quantity of heat flow through refractory lining include the emissivity of the refractory or metal shell, the kind of gases within the furnace atmosphere, and the external convection currents.
