Refractories 
1.Description:
Sintered Mullite is manufactured from pure bauxite and quartz sand.Homogenized mixture is sintered in tunnel kiln with long soaking which better than rotary kiln firing.
2.Characteristics:
Sintered Mullite has a high melting point, excellent resistance to thermal shock, excellent stability under load and good resistance.
3.Application:
High purity Sintered Mullite is used to produce mullite refractory bricks, shapes and monolithics.
