抄録

A process to prepare porous materials has been developed for recycling of the used glass. This process involves two steps, hydrothermal hot-pressing at low temperatures for reaction of glass with water and calcination at high temperatures for foaming. This process dose not require any blowing agents, though the ordinary method to prepare porous materials from glass needs blowing agents such as calcium carbonate and silicon carbide which are decomposed at high temperatures to produce gas. In this process, water incorporated into the glass structure acts as a blowing agent. Thus, this process has following characteristics; easiness to control the foaming temperature, foaming at low temperature in comparison with the ordinary method, and production of porous materials with a fine structure mainly consisting of closed pores.
