This book examines and systematises knowledge concerning porous glass materials. Different volumes of pores and the methods of directly synthesising the glass with predefined sizes are discussed as well. Likewise, the primary approaches on determining parameters of porous structures are a topic of interest within this text. A separate chapter is devoted to properties of porous glass; these include optical, electrical, sensor and transport of it and its materials. Authors provide practical recommendations based on their experience with synthesis as well as handling and applying this specific glass.
