What Are RefractoriesThe Refractories Institute (TRI)

Refractories are ceramic materials designed to withstand the very high temperatures (in excess of 1 000°F 538°C ) encountered in modern manufacturing. More heat-resistant than metals they are used to line the hot surfaces found inside many industrial processes. In addition to being resistant to thermal stress and other physical phenomena

Refractory industrial material Britannica

The property of chemical inertness is of special importance in metallurgy and glassmaking where the furnaces are exposed to extremely corrosive molten materials and gases. In addition to temperature and corrosion resistance refractories must possess superior physical wear or abrasion resistance and they also must be resistant to thermal shock.
