Refractories used in muffle furnace should have low thermal conductivity. The electrical resistivity of refractories drops rapidly with rise in temperature. For reducing spalling tendency the refractory should be well fired and its porosity should be more. Refractoriness under load (RUL) of a refractory is always less than its refractoriness.

Jan 01 1982 · Insulation rarely adds to refractory life and may even reduce it. It does however save energy. In some furnaces for example in the large structures operated at relatively low temperature for annealing boiler equipment the walls are built completely of insulating material using bricks monolithic insulation or fiber blankets.
