Aluminum titanate is a mixture of alumina and titanium dioxide in a certain chemical ratio. The structure belongs to the orthorhombic crystal system. Aluminum titanate ceramic material has a higher melting point (1860℃±10℃) and a lower thermal expansion coefficient (at RT— Under 1000℃, α<2.0×10-6/℃), and has excellent thermal shock resistance. In addition, it has the characteristics of non-wetting with many metals (especially non-ferrous metals) melts and glass melts. Therefore, aluminum titanate ceramics can be widely used in harsh environments such as high temperature resistance, thermal shock resistance, and corrosion resistance.
