ABSTRACT

Glasy specimen was obtained by melting and quenching a borosilicate glas frit mixed with 10~80 wt% EAFdust. The glass transition temperature, Tg of glasy specimen was measured around 550oC from the DTA curve and theheat treatment condition to crystalize a glassy specimen was selected as 70oC/1 hr. The spinel crystal peaks were found incontaining dust > 40 wt%, and the spinel and willemite peaks in dust > 80 wt%. The crystals of several tens of nanometerwith aspect ratio of 0.7~1.0 were observed at a glassy specimen containing dust > 40 wt% by SEM which was not foundby XRD analysis. For the glass-ceramics, the crystals were found in a specimen containing dust of even 10 wt% by SEM.The feature and distribution of crystals observed through the specimen for a glass-ceramics were diverse and not uniform.The crystals found in the glass-ceramics containing 70 wt% dust were hexahedral with an aspect ratio of around unity.Key words Microstructure, Borosilicate, Glas-ceramics, EAF dust, Glas transition temperature, Crystallization, Spinel,Willemite, EDS, XRDEAF dust. ... ..... ... ... .... ..
