【摘要】 借助XRD测试手段研究了Al₂O₃、SiO₂、Fe₂O₃以及MgO几种生料中常见氧化物对高温固硫物相3CaO·3Al₂O₃·CaSO₄形成的影响。结果表明,改变Al₂O₃的含量,不会对3CaO·3Al₂O₃·CaSO₄的形成产生明显影响; Fe₂O₃及MgO的存在能降低3CaO·3Al₂O₃·CaSO₄的形成温度,但也使其分解温度提前;SiO₂的大量存在则会抑制3CaO·3Al₂O₃·CaSO₄的形成。更多还原

【Abstract】 By means of XRD measuring, effects of several common oxidates in raw meal as Al₂O₃, SiO₂, Fe₂O₃ and MgO on the formation of 3CaO·3Al₂O₃·CaSO₄ , the high temperature sulfur solidification physical phase were studied. Study result reveals that changing the content of Al₂O₃ will no obvious effect to 3CaO·3Al₂O₃·CaSO₄ formation; Existence of Fe₂O₃ and MgO will reduce formative temperature of 3CaO·3Al₂O₃·CaSO₄ , but shift its decomposition temperature beforehand; And existence of SiO₂ in great quantity will restrain the formation of 3CaO·3Al₂O₃·CaSO₄.更多还原
