Thermal Conductivity Of High Alumina Bricks-RS Kiln Company

02.08.2018· Thermal conductivity of high alumina bricks are higher than fire clay bricks.The reason is that there are few glass phases with low thermal conductivity in high alumina bricks, while the mullite and corundum crystal with better thermal conductivity increases, which improves the thermal conductivity of products.

Evaluating Refractory Properties - Resco Products

Thermal conductivity is a measurement of the refractory’s insulating ability. In imperial units, thermal conductivity is expressed in units referred to as the “k” factor, whose actual units are BTU-in/ft2- °F-hr. The K-factor is reported at various mean temperatures, which is the average temperature between the hot face surface and the cold face. ASTM specifies thermal conductivity
