description The present invention provides a plate brick having a low amount of generation of smoke and a gas with a pungent odor during use, and exhibiting high durability. A plate brick of the present invention is obtained by: adding an organic binder to a refractory raw material mixture containing 0.5 to 20 mass % of aluminum and/or aluminum alloy; kneading the mixture with the organic binder; forming the kneaded mixture into a shaped body; and subjecting the shaped body to a heat treatment at a temperature of 400 to 1000° C., wherein the plate brick is obtained without being impregnated with a carbon-containing liquid material comprising tar or pitch, after the heat treatment. The plate brick has a compressive strength of 180 MPa or more, and a weight-increasing rate of 1% or less as measured in a hydration test using an autoclave.
