At high temperature the fire clays lose their water of hydration and mainly consist of alumina and silica. The fireclay bricks are manufactured in the same manner as silica bricks. The clay in a finely crushed state is mixed with a definite amount of water in a pug mill. The mixture is then pressed into moulds, dried and finally burnt.

The modification of the silica leads to filler-to-rubber bonds, which increase wear resistance and reduce heat build-up (refs. 3, 12 and 13). Therefore, combinations of carbon black and silica, as long as certain rules are observed, provide an improved compromise with higher performance level than when using carbon black alone (ref. 9).

When heat is added to water, its temperature rises at a rate of 0.56°C (1°F) for each heat input of 2.095 kJ/kg (1 Btu/lb) If we take water at 0°C (32°F) and we add 419 kJ/kg (180 Btu/lb) then we will increase the temperature of the water by 100°C (180°F) This rise in temperature can be detected and is called Sensible Heat
