摘要

摘要: 將鋼渣作為陶瓷的燒制原料之一,設計了CaO-MgO-SiO₂體系陶瓷燒制配方,并成功地制備出性能穩定良好的陶瓷材料樣品.樣品的抗彎強度最大可達99.84 MPa.利用掃描電鏡、電子探針微區分析儀和X射線衍射儀等對鋼渣陶瓷制品進行了分析.結果發現:對于CaO-MgO-SiO₂體系,當鋼渣加入量(質量分數)為40%時,主晶相為透輝石-鐵透輝石固溶體;當鋼渣加入量大于65%時,主晶相為鎂黃長石和透輝石.研究表明,采用鋼渣制備陶瓷材料是一種很有潛力的鋼渣高附加值利用技術.

Abstract: A ceramic with stable and good performances was synthesized by designing the composition of the CaO-MgO-SiO₂ system with steel slag as one of ceramic raw materials.Its bending strength can reach up to 99.84MPa.The ceramic samples were tested and analyzed by scanning electron microscopy(SEM),electron probe microanalysis(EPMA) and X-ray diffraction analysis(XRD).The results show that when the content of steel slag is 40% the dominated crystal phase in the ceramic is a solid solution of diopside and ferric diopside,but when the content of steel slag is higher than 65% the dominated crystal phases are akermanite and diopside.It is indicated that synthesizing a ceramic with steel slag is a promising technology for the utilization of steel slag with high added values.
