Refractory Bricks : Overview, Types, Properties, and Benefits

A fire brick, firebrick, or refractory is a block of ceramic material used in lining furnaces, kilns, fireboxes, and fireplaces. A refractory brick is built primarily to withstand high temperature, but will also usually have a low thermal conductivity for greater energy efficiency. Usually dense firebricks are used in … See more In the making of firebrick, fireclay is fired in the kiln until it is partly vitrified. For special purposes, the brick may also be glazed. There are two standard sizes of fire brick: 9 in × 4+1⁄2 in × 3 in (229 mm × 114 mm × 76 mm) and 9 in × … See more The silica fire bricks that line steel-making furnaces are used at temperatures up to 3,000 °F (1,649 °C), which would melt many other types of ceramic, and in fact part of the silica firebrick liquefies.
