Porous Materials: Process technology and applications / Edition 1 available in Hardcover
- Pub. Date:
- Springer US
This book provides a useful reference for researchers and production engineers in industry. It covers a current 'hot' topic with important applications for energy saving and ecological issues. Basic knowledge of raw materials, evaluation and applications of porous materials are described along with the latest production methods of porous materials including sintering methods, sol-gel processing, and leaching. This interdisciplinary book thus provides a much needed comprehensive and systematic coverage of porous materials, from three internationally recognised authors. The text has been developed from successful short courses run at Materials Research Society meetings.
