A high alumina refractory of improved resistance to deformation at high temperature and resistance to slag penetration is made with a coarse fraction (+28 mesh) containing calcined flint clay and a fine fraction (-65 mesh) of fine silica, such as volatilized silica, and fine alumina. The intermediate fraction 28 x 65 mesh) can be either calcined flint clay or alumina, or a mixture of these two, selected to obtain the properties and Al2O3 content desired in the composition. |
