【摘要】 以粉煤灰和钢渣为主要原料，滑石和钾长石作为助熔剂，使用原位发泡法制备发泡陶瓷，系统探讨了原料组成对泡沫陶瓷物理性能、矿物组成及孔隙结构的影响。结果表明：高温烧结可在不添加发泡剂的情况下实现优异的自发发泡效果；最佳制备工艺为m（粉煤灰）:m（钢渣）:m（滑石）:m（钾长石）=60:20:10:10，此时发泡陶瓷的体积密度为0.90 g/cm~3，抗弯曲强度为9.74 MPa，吸水率为10.05%，总气孔率为71.95%，闭孔率为65.68%。更多还原

【Abstract】 This study uses fly ash and steel slag as primary raw materials,with talc and potassium feldspar as fluxing agents,to prepare foamed ceramics via the in-situ foaming method. The study systematically investigates the influence of raw material composition on the physical properties,mineral composition,and pore structure of the foamed ceramics. The results indicate that high-temperature sintering can achieve significant spontaneous foaming effects without the addition of foaming agents. The optimal preparation process was determined to be a mass ratio of fly ash:steel slag:talc:potassium feldspar of 60:20:10:10. At this ratio,the samples exhibited the following characteristics:bulk density of 0.90 g/cm~3,flexural strength of 9.74 MPa,water absorption rate of10.05%,total porosity of 71.95%,and closed-cell porosity of 65.68%.更多还原
