摘　　要：以工业废弃高炉渣为主要原料,采用一次烧结法制备了微晶玻璃釉面砖.高炉渣的组成为CaO、SiO_2、Al_2O_3、少量Fe2O3及TiO_2等.当高炉渣粒度为3.3μm,原料配比为高炉渣80wt%、钾长石10wt%、滑石10wt%时,800℃保温30 min,1 160℃保温1.5 h制得样品.样品的吸水率为0.12%,显微硬度为6.5 GPa,抗弯强度为128 MPa,满足GB/T3810对釉面砖性能要求.微晶玻璃主晶相为硅灰石(含少量钙长石),晶粒1μm左右,晶体形貌为球状和针状.Glazed tiles of glass-ceramics were prepared by direct sintering using blast furnace slag as main raw material.The results showed that the composition of blast furnace slag was glass phase,which chemical composition was CaO,SiO 2,Al 2O 3,a little of TiO 2,and Fe 2O 3.When particle size was 3.3μm;the content of blast furnace slag was 80wt%,potassium feldspar was 10wt%,talc was 10wt%;crystallizing at 800℃for 30 min and sintering at 1 160℃for 1.5 h.The sample’s water absorption was 0.12%,micro-hardness was 6.5 GPa;flexural strength was 128 MPa,which met the GB performance requirement of glazed tile.The main crystal phase of glass-ceramics was wollastonite(contain a little of anorthite).Crystal size was about 1μm and the morphology of crystal was globular and needle-like.
