Investigation Of The Properties Of Low Dielectric Constant Aluminosilicate Glass Produced From Blast Furnace Slag

In this paper, aluminosilicate glasses were prepared from blast furnace slag, quartz sandand emery. The structure, density, crystallization temperature and dielectric properties wereinvestigated systematically. The results suggested that the properties of the as made glasswere better than those of E glass. In addition, the effects of composition on the structure andproperties of aluminosilicate glass were studied.Firstly, aluminosilicate glasses were prepared from blast furnace slag and quartz sand.The density and crystallization temperature increased with increasing SiO2content. Thus theincrease in SiO2content strengthened the rigidity of glass network. As a result, the dielectricconstant and loss decreased. Secondly, aluminosilicate glasses were prepared from blastfurnace slag, quartz sand and emery. The density and crystallization temperature decreasedwith increasing Al2O3content. The increase in Al2O3content weakened the rigidity of glass.As a result, the dielectric constant and loss increased. Finally, the effects of othercompositions on the structure and properties of aluminosilicate glass were studied. Thedensity and crystallization temperature increased with increasing Al2O3content on theexpense of modifier content. Thus the increase in Al2O3content strengthened the rigidity ofglass. As a result, the dielectric constant and loss decreased. The density and crystallizationtemperature increased with increasing SiO2content on the expense of modifier content. Thusthe increase in SiO2content strengthened the rigidity of glass. As a result, the dielectricconstant and loss decreased. The density and crystallization temperature increased withincreasing SiO2content on the expense of Al2O3content. Thus the increase in SiO2contentstrengthened the rigidity of glass. As a result, the dielectric constant and loss decreased.
