Mullite is calcined form of kyanite with a medium-sized acicular particle shape (needle-shaped) and high-temperature stability. It can be added to a clay body to check thermal expansion. It adds strength because of the needle-like shape of its crystals. It is also used as a lower cost alternative to alumina, with slightly better thermal shock properties.
