We have the capability to supply customized material of Homogenized Sintered Mullite ranging from 47% of Al2O3 content to 70% of Al2O3 content.

Our offered Mullite is a synthetic material. It is chemically synthesized by mixing the right proportions of other alumina rich raw materials such as clays, pure kaolin and bauxite, then eliminating impurities, extrusion in form of sticks, and finally calcining the mixture after at high temperatures.

Homogenized Sintered Mullite offered by Thyme are calcined in rotary kilns or tunnel kilns at 1450 degree C to 1700 degree C, with holding time for 4-24 hours, which guarantees the synthetic reaction progress completion, to achieve the highest mullite crystal content and uniform structure.

The thermal expansion coefficient of this material is uniform and is much lower than corundum and silica, thus it provides excellent thermal shock resistance. The performance of RUL and high temperature creep is good. High hardness and excellent chemical corrosion resistance are some more advantages of this material.
