Auteur : Office québécois de la langue française,Définition
A type of brick that can withstand high temperatures in presence of flame or hot gases. The important characteristics of a good fire-brick are: 1) resistance to melting or softening at high temperatures; 2) resistance to erosion by the action of molten slag in furnace linings; 3) resistance to erosion by hot ash-laden gases in chimneys; 4) resistance to spalling when subjected to sudden change of temperature; 5) mechanical strength should not decrease with rise of temperature. These properties are usually compatible with a good thermal conductivity, and thus fire-bricks often need to have a provision of good thermal insulation.
