【摘要】：利用高爐渣及其它輔助原料制備基礎(chǔ)玻璃,采用一步燒結(jié)法制備主晶相為輝石的CaO-MgO-Al_2O_3-SiO_2(CMAS)微晶玻璃。綜合運(yùn)用DSC,XRD以及場發(fā)射掃描電子顯微鏡等測試手段,分析熱處理制度對高爐渣CMAS微晶玻璃的析晶行為及性能的影響。結(jié)果表明:隨著熱處理溫度上升,微晶玻璃的主晶相均為輝石,次晶相均為長石,晶相析出量增加,微晶玻璃的體積密度及抗折強(qiáng)度均呈現(xiàn)先增后減趨勢。隨著熱處理時(shí)間增加,微晶玻璃的體積密度及抗折強(qiáng)度均呈現(xiàn)下降趨勢。當(dāng)熱處理溫度為1020℃,晶化時(shí)間30 min時(shí),樣品的機(jī)械性能最好,體積密度為2.690 g·cm~(-3),抗折強(qiáng)度為67.00 MPa。
[Abstract]:The basic glass was prepared from blast furnace slag and other auxiliary materials. CaO-MgO-Al2O3-SiO2CMAS-based glass-ceramics with main crystal phase as pyroxene were prepared by one-step sintering method. The effect of heat treatment on the crystallization behavior and properties of CMAS glass-ceramics in blast furnace slag was analyzed. The results showed that the main crystal phases of glass-ceramics were pyroxene, the sub-crystalline phases were feldspar, and the amount of precipitates increased with the increase of heat treatment temperature. The bulk density and flexural strength of glass-ceramics increased first and then decreased. With the increase of heat treatment time, the bulk density and flexural strength of glass-ceramics decreased. When the heat treatment temperature was 1020 鈩，
