Form: Foam
Formula: Al₂O₃
Material: Alumina
CAS Number: 1344-28-1
Commodity: Ceramics
Alumina Foam is part of our extensive range of advanced ceramic materials. A rigid foam it has a highly porous structure with low density and high surface area. Its key properties include high temperature resistance, low thermal conductivity and high compressive strength. Alumina Foam is used in applications such as thermal insulation for high temperature furnaces, catalytic converters and lightweight structural components. We offer Alumina Foam in a range of 6 options for a choice of pore and porosities to suit different applications.
