Aluminium Titanate

Description

Aluminium titanate ceramics are synthetic advanced ceramic materials composed of alumina and titanium oxide compounds. It has a very low coefficient of thermal expansion, high temperature resistance and low thermal conductivity. Aluminium titanate ceramics are often used in the metallurgical and automotive industries.
