Abstract
The authors have applied hydrothermal reactions to develop recycling processing of slag or glass. As an example, under hydrothermal conditions such as 200～300oC and 30～40MPa with H2O, powders made of glass can be sintered to become solidified glass materials containing about 10mass% H2O. When the glass containing H2O is heated again under normal pressure, the glass expands releasing H2O to make porous microstructure. H2O starts to emit just above the glass transition temperature. Therefore, when we have a glass with low glass transition temperature, we can make low temperature foaming glass. The SiO2-Na2O-B2O3 glass is a candidate to be such a foaming glass. In this paper, we describe our recent trial on the fabrication of the low temperature foaming glass by using hydrothermal reaction.
