Cerachem Blanket is used extensively in high temperature units in the ceramic, chemical processing, and ferrous metal industries. Thermal conductivity (often denoted k, , or ) is the property of a material to conduct heat. It is evaluated primarily in terms of the Fouriers Law for heat conduction. In general, thermal conductivity is a tensor property, expressing the anisotropy of the property. In Imperial units, thermal conductivity is measured in BTU/(hrftF). Other units which are closely related to the thermal conductivity are commonly used. thermal conductivity. Enter a value into either text box and select units using the drop-down boxes.
