A Review of Porous Glass-Ceramic Production Process, Properties and Applications

Abstract Porous materials exist around our environment and play an important role in our daily lives to be used widely in many fields, among the fields are energy distribution and storage, vibration suppression, liquid filtration, heat insulation, and sound absorption. Porous glasses are materials that have pores structure using silica as the primary component in all types of standard and specialty glass mixture with a foaming agent and other additives. Porous glass is usually in the size of nanometre and micrometer range. Porous glass is usually prepared by using phase separation, sintering and sol-gel method [1]. This review paper will focus on the various properties of this porous material related to the production process used to their properties and possible applications such as filtering, lightweight concrete, heat resistance insulator, and biomaterials.
