AB - Glas-ceramics were fabricated by heat-treating a glas at 700oC/10 hr which was obtained by melting a glasfrit mixed with 40~80 wt% EAF dust at 1300oC/1 hr. Dependence of crystal phase and bonding state change upon aleaching procedure (TCLP) test data to investigate a chemical durability of the specimens. Increasing dust in a glass shiftedthe peak around 10 cm1 to the lower frequency which was composed of two vibration peaks for the nonbridging oxygenat 960 cm1 and the bridging oxygen at 1050~1060 cm1. Also, the B2O3 structure of boroxol ring changed to a tetrhedral-,trigonal- and di-borate with dust addition. The Fe-O peaks in the glas-ceramics were observed which is consitent witha glass-ceramics ater TCLP test so the chemical durability of the glass-ceramics is superior than that of glass. The leachingconcentration of Fe for the glass-ceramics containing EAF dust 80 wt% is 1/15 times lower than that of glas. The Znleaching concentration for the glass-ceramics containing dust < 70 wt% was higher than that of glass but its trend wasreversed for the specimen of dust content > 80 wt% which could be concluded as corelated with occurence of wilemitephase.Key words EAF dust, Borate glass, Glas-ceramics, Heavy metal, Stabilization, Chemical durability, Spinel, Willemite,FT-IREAF dust. ... ..... ... ... .. . ... ........ ...†
