Abstract
Since a large amount of blast furnace (BF) slag is generated, its new recycling processes for the production of valuable materials have been required. Development of reusing method for waste glasses is also strongly demanded. The authors have tried to fabricate porous materials from those two materials by using the hydrothermal treatment. In the present work, hydrothermal hot pressing technique was conducted at 250-350°C. From BF slag, a heat-insulating material was obtained, possessing the low thermal conductivity of 0.25 W / m K. SiO2-Na2O-B2O3 glass was converted into glass containing water which exhibits the foaming as low as 200°C and becomes porous glass material.
