Web15 de jun. de 2024 · What Does Refractory Brick Mean? Refractory brick is a ceramic material that is normally used in high-temperature environments because of its lack of flammability and because it is a decent insulator, which reduces the amount of energy loss. Refractory brick is typically comprised of aluminum oxides and silica. It is also known … WebRefractory materials are classified into three types based on fusion temperature (melting point). Normal refractories have a fusion temperature of 1580–1780 °C (e.g. Fire clay) High refractories have a fusion temperature of 1780–2000 °C (e.g. Chromite) Super refractories have a fusion temperature of > 2000 °C (e.g. Zirconia)
