高炉渣和低碳铬铁合金渣协同制备微晶玻璃
Cooperative Preparation of Glass-ceramics by Blast Furnace Slag and Low-carbon Chromium Iron Alloy Slag
摘要
Abstract
This is an article in the field of mineral materials.In order to make high-value utilization and harmless treatment of bulk industrial solid waste,CaO-MgO-Al2O3-SiO2-Cr2O3 system glass-ceramics were prepared by melting method with Baotou Steel blast furnace slag,low-carbon chromium iron alloy slag and quartz sand as the raw materials.The optimum ratio of raw materials was explored by means of differential thermal analysis(DSC),X-ray diffraction(XRD)and scanning electron microscopy(SEM).The results showed that when the mass ratio of blast furnace slag,low-carbon chromium iron alloy slag and quartz sand was 60∶40∶31,the crystalline phases of glass-ceramics were diopside and omphacite.At this time,the performance of glass-ceramics was the best,the flexural strength reached 126.25 Mpa,the crystallinity reached 89.19％,and the microstructure was ideal.The glass-ceramics prepared under the optimal raw material ratio met the requirements for national class A decoration materials,i.e.Ira≤1.0 and Iγ≤1.3,and the leaching concentration of heavy metal chromium in the glass-ceramics met the national standard,indicating that it is feasible to prepare glass-ceramics with blast furnace slag and low-carbon chromium iron alloy slag.关键词
