If you are looking for customized and cheap high alumina mullite insulating brick made in China from a high alumina mullite insulating brick factory, Zibo Qunhui Refractory Co.,Ltd is always at your service.
insulating brick
Description:
We supply several grades of mullite insulating brick for use in applications from 1260°C to 1760°C.Each grade of brick is formulated to meet specific thermal and physical requirements.After firing each brick is machined to close dimensional tolerances.Insulating bricks are manufactured utilising exceptionally high purity clays and other ceramic materials.The carefully graded organics which are used during the manufacturing process burn out during firing to give a uniform pore structure.
