【摘要】：以钡渣和高岭土为原料,采用固相烧结法制备钡渣陶瓷砖,通过抗压强度、吸水率及X射线衍射仪(XRD)分析,研究了烧结温度对钡渣陶瓷结构和力学性能的影响。研究表明,随着烧结温度升高,钡长石相逐渐增多,晶粒尺寸增大,晶格应变减小,吸水率降低。此外,1100℃烧结的陶瓷具有最佳力学性能,此温度下十二烷基硫酸钠(SDS)添加量为0.8%的陶瓷样品与不含SDS样品相比相结构组成相似,但SDS添加量为0.8%样品抗压强度和吸水率表现更优。因此,合适的烧结温度与SDS添加量都对陶瓷材料的相结构组成、晶粒尺寸、晶格应变、抗压强度和吸水率有重要影响。
[Abstract]:Barium slag ceramic tiles were prepared by solid phase sintering from barium slag and kaolin. The effect of sintering temperature on the structure and mechanical properties of barium slag ceramics was studied by means of compressive strength, water absorption and X-ray diffraction (XRD) analysis. The results show that with the increase of sintering temperature, the barium feldspar phase increases gradually, the grain size increases, the lattice strain decreases and the water absorption decreases. In addition, the ceramic sintered at 1100 鈩，
