摘要:: 利用X荧光、X-ray和DTA等技术分析高炉渣原料的成分、晶相组成和热学性能,并以冶金高炉渣为主要原料添加少量长石,通过较简单的烧结法制备出CaO-Al2O3-SiO2-MgO 4元系为基础的微晶玻璃,测试分析炉渣微晶玻璃的性能.结果表明,炉渣微晶玻璃晶相主要为钙黄长石,样品的吸水率为0.1%,维氏硬度为5～6 GPa,三点弯曲强度为60～70 MPa,其性能明显优于黏土砖.

Abstract:: X-fluorescence, X-ray and DTA were used to analyze the composition, crystal phase composition and thermal properties of blast furnace slag raw materials, and a small amount of feldspar was added to metallurgical blast furnace slag as the main raw material, and CaO-Al2O3-SiO2-MgO 4-member-based glass-ceramic was prepared by a relatively simple sintering method, and the properties of slag glass-ceramic were tested and analyzed. The results show that the slag glass-ceramic crystal phase is mainly calcium, the water absorption rate of the sample is 0.1%, the Vickers hardness is 5~6 GPa, and the three-point bending strength is 60~70 MPa, and its performance is significantly better than that of clay brick.
