We normally carry out MgO refractory work in CS2 furnace where reaction temperature is from 1200 to 1300deg centi . We normally add sulphur and charcoal in furnace.

refractory is the lining provided in furnaces with alumina,magnesia etc to protect the steel structure from collapsing due to thermal stress.
refractory materials are by definition materials which can withstand high temperatures without collapsing

Refractories are heat-resistant materials that constitute the linings for high-temperature furnaces and reactors and other processing units. In addition to being resistant to thermal stress and other physical phenomena induced by heat, refractories must also withstand physical wear and corrosion by chemical agents. Refractories are more heat resistant than metals and are required for heating applications above 1000°F (538°C).

refractory is a clay object made up by moulding and then heating it at higher temperatures in a furnace,e.g. a brick is a refractory.
