AB - Microstructures of fre surface and interior of glass-ceramics obtained by heat treating silicate glass specimencontaining electric arc furnace dust (EAF dust) were observed. The crystallization temperature, Tc of glassy specimen wasmeasured around 850ospecimen was selected as 950oC for 1 hr. Glass specimens containing 50 wt% dust were amorphous, while glass specimenscontaining 70 wt% dust showed spinel crystal peaks in XRD results. In case of glass-ceramic specimens, spinel crystalinephase was appeared with willemite, and willemite crystal peak intensity increased with increasing dust contents. Thefractured surface of glas specimens containing 50 wt% dust was smooth like mirror surface, but that containing 70 wt%dust showed spinel crystals of 10m size in glass matrix. In case of glass-ceramic specimens, ZnO crystal particles of2~5 m size were produced in free surface and glassy phase, spinel and wilemite crystal phases existed in interior. Therewere no crystals in glasses containing 50 wt% dust, while glas containing 70 wt% dust had 14 vol% crystals. Crystalinityof glas-ceramic specimens containing 50 and 70 wt% dust were 19 and 43 %, respectively. When microstructures of glassand glass-ceramic specimens were observed through SEM after TCLP experiment, glass specimens showed flakingphenomenon while glass-ceramic specimens showed a slight corosion evidence without any cracks.Key words
