GENERAL DESCRIPTION

Ceramics based on Allied foams have fine pore size, excellent stability and high integrity. Foam Ceramics can be as light as < 20 pcf ( 323 kg/m³ ) and with use temperatures as high as > 3,000^oF (see blocks on left).. A fiber re-enforced foam ceramic crucible under scorching torch is shown on right.

APPLICATIONS

Unlike the sol-gel method and the burnout of slip-impregnated organic foams, foam ceramics from Allied foams are simple to make while they surpass conventional foam ceramics and firebricks in pore texture, mechanical strength and temperature shock resistance. They are suitable for the manufacture of long-lasting ceramic tiles, electronic ware, fire bricks and other insulative materials for high temperature applications.
