Refractories and Classification of Refractories IspatGuru

Apr 30, 2017· Refractories and Classification of Refractories. Refractories are inorganic, nonmetallic, porous and heterogeneous materials composed of thermally stable mineral aggregates, a binder phase and additives. The principal raw materials used in the production of refractories are normally the oxides of silicon, aluminum, magnesium, calcium and zirconium.

11.5 Refractory Manufacturing

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.
