Description
CT firebricks are made from high-purity refractory clays, temperature of use ranging from 1100°C to 1700°C, each grade is formulated to meet specific thermal and physical requirements.
These high alumina bricks comes with graduated additions of alumina for higher temperature products.
Carefully graded organic filler.
The organic filler burns out during manufacture to give a uniform, control pore structure.
