Thermal Conductivity

The graphical data shown in this leaflet is derirved from tests based on ASTM C201 method, which is the recommended test method for fibrous products by the European Federation of manufacturers of refractory products. Non-Air atmospheres can exert a marked influence on the effective conductivity. We therefore recommend that the use of Ceramic Fibre in special atmospheres is discussed with our sales /application engineers. An interesting feature is the trend of decreasing conductivity with increasing fibre density for the same grade of ceramic fibre. This holds up to a density of about 300 kg/m3, remaining constant to around 400 kg/m3. The explanation lies in the fact that measured values are total conductivities representing the combined heat transfer from radiation, convection, and conduction (of fibre and air) through the highly porous material. The relative importance of individual modes varies both with temperature and fibre density.

 

Continuous Service Ratings

The normal continuous service temperatures are approximately 100C below classification temperature in air or oxidising atmospheres and apprnximately 200C lower in highly reducing atmospheres. However, the upper temperature limit depends on requirements of specific applications. Practical experience is likely to provide the final recommendation. The figures quoted as continuous service temperatures are given as a guide, taking into account likely changes in properties such as resiliency and shrinkage, resulting from devitrification on the individual fibres.

Our sales/application engineers will be glad to advise in specific
cases.
