Refractory Density

The density of refractory materials is often measured in pounds per cubic foot (pcf) in imperial units. The density can range widely depending on the type of refractory and its composition. Dense refractories generally have densities in the range of 94 to 220 pcf (1,500 to 3,520 kg/m³), while insulating refractories typically have lower densities, ranging from 40 to 150 pcf (640 to 2,400 kg/m³). These values can vary based on the specific formulation of the refractory material and its intended application.
