Basic refractories consists mainly of basic oxides without free silica and resist the action of bases. The most common basic refractories are Magnesite, Dolomite, lime etc. But lime, because of its dehydrating tendency is never used as a refractory. Magnesite: This is most important basic refractory material.

Dolomite is sometimes used both in the raw and calcined form as refractory material for hearth maintenance and for banking door in open hearth furnaces. For most refractory uses, it is desirable to subject the dolomite to a heat treatment at a high temperature of the order of 1700ºC, to shrink the material thoroughly and render it less reactive.
