Fire clay brick and high alumina brick are both belonging to Al2O3-SiO2 bricks. They can be divided into standard shapes and special shapes. Standard shapes have dimension that are conformed by most refractory manufacturers and are generally applicable to kilns or furnaces of the same types. Standard shapes are usually bricks that have a standard dimension of 9 × 4 1⁄2 × 2 1⁄2 inches (230 × 114 × 64 mm) and this dimension is called a "one brick equivalent". There are ranges of standard shapes of different sizes manufactured to produce walls, roofs, arches, tubes and circular apertures etc. Special shapes are specifically made for specific locations within furnaces and for particular kilns or furnaces.
