Study on preparation of CaO-Al2O3-SiO2 system glass derived from molten blast furnace slag

摘要

The optimum parameters of experiments were well defined through a large number of orthogonal tests.As samples were investigated with DTA,XRD,SEM and other modern research methods,the microscopic dynamics of glass formation was researched.It was reported that product glass could be directly prepared of molten blast furnace slag and the rate of utilization could reach 70％.The performances of samples,such as bending strength,acid and alkali resistance,etc.,were better than ordinary marble.
