Product Description


Mullite is a material that is manufactured by combining Alumina with Silica, fused together during sintering,
in various combinations to produce a family of materials. Known as Mullite for the dense materials and
Porous mullite or corundum for the porous grades.Synthetic Mullite (Al2O3-SiO2) products are available
in both impervious and porous forms.
 
1.Densely sintered (impervious) mullite combines high strength with good thermal shock resistance.
2.Porous mullite have a reasonably high strength combined with low thermal expansion giving improved
levels of thermal shock.
 
5: Materials:  mullite ,  clay ,or high alumina materials  as per buyer request.
