Carbon and Silica foams are of great interest because of their properties like lightweight, low density, high chemical resistance, excellent thermal shock resistance and potential ability of their physical properties from insulator to conducting material. Numbers of methods used for the development of carbon and silica foam are known. In this book, the replica method has been used for the development of carbon and silica foams. The carbon and silica foams have been characterized for their composition, physical, thermal, microstructure and mechanical properties. Hence, this book will surely help you to provide significant knowledge about Foams.
