Synthetic sintered mullite


Sintered Mullite or sometime called Homogenized Bauxite is is characterized by an outstanding homogeneous phase composition, very low pollution, and an absolute micro-crystallinity. The last property conveys its excellent physical parameters, such as the high thermal shock resistance,and very stable performance with its low thermal expansion, low Fe2O3 content,high density and uniformity.

Description

Sintered Mullite or sometime called Homogenized Bauxite is is characterized by an outstanding homogeneous phase composition, very low pollution,

and an absolute micro-crystallinity. The last property conveys its excellent physical parameters, such as the high thermal shock resistance,and very stable

performance with its low thermal expansion, low Fe2O3 content,high density and uniformity.
