Description
An infusible material that can withstand high temperatures without melting or cracking. Fireclays are most refractory when they contain a high proportion of Alumina (at least 45%) in Silica with less than 5% impurities such as Iron, Lime, and Magnesia. This high duty grade fireclay can generally withstand temperatures to at least 1600C and it is used for making firebrick, kiln linings, muffle furnaces, and crucibles. Common fireclays have 35-37% alumina.
