Ceramic Brick Heat Capacity

Calculate the temperature change when 400 kj of thermal energy is transferred to a 3 50 kg brick.

Ceramic brick heat capacity.

When the sun is shining into a room and the air is warm heat will be absorbed by the walls floor and other surfaces in the room. The silicate brick gives indicators of 0 75 0 8 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. Chamotte is capable when heated to increase the heat capacity from 0 85 to 1 25.

Ceramic materials properties physical properties of ceramics. Heat capacity the heat capacity of a substance is the amount of heat required to change its temperature by one degree. For products from clay and ceramics this indicator ranges from 0 7 0 9 kj kg. Brick densities densities of common types of bricks.

Honeycomb ceramic regenerator brick honeycomb ceramic regenerator are mainly made of cordierite mullite cordierite corundum mullite corundum and silicon carbide which has many significant advantages such as low heat expansion high specific heat capacity high specific surface area low pressure drop good thermal conductivity good. For example a brick wall has higher thermal mass than a timber framed cavity wall so it will absorb more heat than a timber framed wall of the same thickness.
