Ceramic materials properties physical properties of ceramics.
Ceramic brick heat capacity.
For products from clay and ceramics this indicator ranges from 0 7 0 9 kj kg.
Where w is stored heat in kj sq m r is bulk density of brick in kg cu m cpm is mean specific heat of the refractory bricks between the temperatures t1 and t2 in kj kg k s is wall thickness in meters t1 is the inside temperature of furnace wall in deg c and t2 is the external temperature of the furnace wall in deg c.
Calculate the temperature change when 400 kj of thermal energy is transferred to a 3 50 kg brick.
Comparison with other materials.
Heat capacity the heat capacity of a substance is the amount of heat required to change its temperature by one degree.
The specific heat capacity of brick is 840 j kg c.
Chamotte is capable when heated to increase the heat capacity from 0 85 to 1 25.
Electric heating of a mass electric heating of an object or mass energy supply and temperature change.
Brick densities densities of common types of bricks.
The silicate brick gives indicators of 0 75 0 8 kj kg.
