CT firebricks are made from high-purity refractory clays; temperature of use ranging from 1100°C to 1700°C and each grade is formulated to meet specific thermal and physical requirements. For higher temperature products, their additions of alumina are graduated. Each grade is added by classified organic fller. This organic fllr burns out during manufacture process to give a uniform and controlled pore structure.

Low thermal conductive, low heat storage

Light weight, purity

Good thermal insulation, enable the use of thin-walled constructions

The good alumina contents confer good refractoriness

Low iron and alkali fluxcontent contributes to their stability to reducing atmosphere

These can be machined to special shapes, incurring fewer sections and joints

Recommended for use as primary hot face refractory lining or as back-up insulation behind other refractories in furnaces, kiln, flues, heaters, regenerators, stress relieving furnaces, etc
