Abstract
A lightweight refractory is disclosed which is a shaped porous body having refractory particles and aluminous short fibers bound to each other with mullite. The crtystalline structure of the refractory is chiefly composed of mullite and corundum. The mullite content is at least 12 mol % of the sum of mullite and corundum. The refractory is substantially free of free silica.
