Preparation of Foam Glass Composite from Iron Ore Tailing

Abstract:

Article Preview

Foam glass composite with good capabilities was prepared from iron ore tailings as the main material by two steps. The phase composition and microstructure were determined by X-ray diffraction and scanning electron microscopy. The effects of foaming temperature and sintering temperature on sample capabilities were studied by determining sample bulk density and compression strength. The results show that the main phase of basis glass powder is amorphous mineral. The foam glass composite with enclosed circle pore mainly concludes Ca[(Fe,Mg)][SiO3]2 and amorphous glass. The diameter size of pore is wide and distributes evenly. The foam glass composite, whose compression strength is 62.25MPa, and bulk density is 2.056 g/cm3, has fine complex capabilities. With the increase of foaming temperature the sample pore diameter size raises, while bulk density and compression strength reduces. The bulk density and compression strength all diminish firstly and raise subsequently with the sintering temperature increasing. The optima temperature parameters are foaming temperature of 900~950 and sinter temperature of 1100 .
