Abstract

The effect of CaO/SiO₂ ratio on the crystallization behaviors, mechanical properties, and acid and alkali resistance properties of the prepared Ti-bearing blast furnace slag-based glass ceramics were investigated. The results showed that the crystallization temperature obviously decreased with the increase of CaO/SiO₂ ratio, and the higher CaO/SiO₂ ratios leaded to stronger crystallization ability. The main crystal phases transformed from CaAl₂Si₂O₈ and CaMgSi₂O₆ to CaAl₂Si₂O₈, CaMgSi₂O₆, and Ca₂MgSi₂O₇ as the CaO/SiO₂ ratio increased from 0.3 to 0.6. When the CaO/SiO₂ increased to 0.5, a small amount of akermanite precipitated. The vickers hardness gradually decreased, and the flexural strength first increased and then decreased with an increased CaO/SiO₂. The glass ceramic with CaO/SiO₂ = 0.5 exhibited the highest flexural strength of 109.58 MPa. The prepared glass ceramics showed good acid and alkali resistance (> 98.30%), especially alkali resistance. Therefore, the best candidate for CaO/SiO₂ ratio in the investigated Ti-bearing blast furnace slag-based glass ceramics was selected as 0.5. This work can provide the reference for preparation slag-based glass ceramics.

不同CaO/SiO2质量比含ti高炉渣基玻璃陶瓷的结晶行为与性能

研究了CaO/SiO2配比对制备的含钛高炉渣基玻璃陶瓷结晶行为、力学性能和耐酸碱性能的影响。结果表明:随着CaO/SiO2比的增大，结晶温度明显降低，且CaO/SiO2比越高，结晶能力越强;当CaO/SiO2比从0.3增加到0.6时，主要晶相由CaAl2Si2O8和CaMgSi2O6转变为CaAl2Si2O8、CaMgSi2O6和Ca2MgSi2O7。当CaO/SiO2增加到0.5时，有少量铁长石析出。随着CaO/SiO2含量的增加，材料的维氏硬度逐渐降低，抗弯强度先升高后降低。当CaO/SiO2 = 0.5时，玻璃陶瓷的抗折强度最高，达到109.58 MPa。制备的玻璃陶瓷具有良好的耐酸、耐碱性能(> 98.30%)，尤其是耐碱性能。因此，所研究的含钛高炉渣基玻璃陶瓷中CaO/SiO2的最佳候选比为0.5。本工作可为渣基玻璃陶瓷的制备提供参考。
