Why is Duocel® silicon carbide foam so special?
The matrix of cells and ligaments is completely repeatable, regular, and uniform throughout the entirety of the material. Duocel® silicon carbide (SiC) foam is a rigid, highly porous and permeable structure and has a controlled density of metal per unit volume.

*these values were derived from small samples where edge effects influenced the results. Larger samples having a minimum of 10-15 bubble diameter produce more general test results which are in better compliance with the equations.
Duocel® silicon carbide (SiC) foam is a great thermal conductor at lower temperatures.
Please visit our thermal conductivity page in the technical data section for a more in depth explanation of how materials and properties effects the thermal conductivity of Duocel® foam.
Duocel® silicon carbide (SiC) foamcan be used in electrochemical processes that require low electrical and fluid flow resistance. This is in stark contrast to most ceramics, which do not conduct electricity. Duocel® SiC supplements its strength in this type of application with its increased ability to withstand extreme temperatures.
Please visit our electrical conductivity page in the technical data section for a more in depth explanation of how materials and properties effects the electrical conductivity of Duocel® foam.
Duocel® silicon carbide (SiC) foam can be made up to 1” thick at 100 PPI. Larger pore sizes can be made larger. Please contact us for more info.
Duocel® silicon carbide (SiC) foam resists oxidation up to 3002F. SiC also has high resistance to acid corrosion.
It has a hardness that reduces the mechanical wear of the surface of Duocel® SiC foam.
ERG does not sell foam as a raw bulk material, only as finished end item components.
