高炉渣含量与热处理制度对矿渣微晶玻璃性能的影响
Effects of the Content of Blast Slag and Heat-treatment Parameters on the Properties of Slag Glass-ceramics
摘要
Abstract
A glass-ceramics of CaO(MgO)-Al2O3-SiO2 system was prepared by melting with blast slag and other mineral materials as starting materials, and CaF2, P2O5, Fe2O3 as multiple nucleation agents. DTA, XRD and SEM were used to ascertain the heat-treatment temperatures and characterize the phase composition and microstructure of the glass-ceramics. The relationship among the content of the blast slag, the heat-treatment parameters and the properties were discussed. Experimental results show that when the content of the slag was 45%, the major crystalline phases are wollastonite (CaSiO3) and diopside (CaMg(SiO3)2), and the properties of the glass-ceramics are as required. The optimal heat-treatment parameters are: annealed at 670 ℃, nucleated at 850 ℃ for 1 h, then crystallized at 970 ℃ for 1 h. The proper rate for heating is 5～6 ℃/min before 850 ℃, 1～2 ℃/min between 850 ℃ and 970 ℃.关键词
