Description

Fireclay bricks are manufactured from unfired refractory bond clay and fireclays (chamotte), fired refractory clay or similar grog materials . Fireclay refractory bricks have two main components namely 38 % to 45 % of alumina (Al2O3) and  50 % to 60 % of silica (SiO2).

The variety of clays and manufacturing techniques allows the production of numerous brick types appropriate to particular applications. The usefulness of fireclay refractory bricks are largely due to the presence of mineral mullite, which forms during firing and is characterized by high refractoriness and low thermal expansion.

Important characteristics of fireclay refractory bricks:The softening behaviour of fireclay refractory bricks is determined by the amount and the composition of the glassy phase. Due to the alkali content and the presence of other impurities, this phase starts to soften at 1000 deg C and it imparts a high softening interval to the fireclay bricks because of its high viscosity. The softening behaviour of fireclay bricks are determined by testing the bricks for refractoriness under load (RUL), thermal expansion under load (creep), and hot crushing strength.
