Abstract

Hydrothermal treatment has been conducted to create porous glass or ceramics as value-added materials for the recycling of slag and glass. Under hydrothermal conditions, slag and glass react with a high pressurized H2O and hydrate glass phase containing plenty of H2O is formed to connect raw materials particles to make ceramic materials. The hydrothermal process takes advantages of energy costs, because it can be operated at a low temperature compared to conventional sintering processes. Since the hydrothermal process uses H2O to fabricate ceramic materials, it can be regarded as energy-saving, eco-friendly, and spontaneous materials processing. In the present study, we introduce some applications of hydrothermal treatments to slag / glass to produce functional porous ceramic materials.
