摘　　要：用苎麻纤维织物作为生物模板,聚合氯化铝作浸渍液,经过浸渍和干燥制备氧化铝陶瓷预制体,将氧化铝陶瓷预制体分别在1350℃、1400℃、1450℃、1500℃、1550℃下进行有氧煅烧制备出氧化铝陶瓷。利用XRD、TEM等技术对其各项性能进行分析。结果表明:不同烧结温度对氧化铝陶瓷的显气孔率、真实密度有很大影响,并且增大了晶粒大小和改善了孔隙的分布,其中烧结温度为1500℃时得到的氧化铝陶瓷性能是最好的。This study takes ramie fabric as the template and polyaluminium chloride as the impregnation liquid,preparing alumina ceramic precast body by impregnating and drying.Then alumina ceramics are produced by aerobic calcinations by burning the alumina ceramic precast bodies respectively in temperature of in 1350 ℃,1400 ℃,1450 ℃,1500 ℃,1550 ℃.Analyses are made of the alumina ceramics＇ performance by means of XRD,TEM,etc.The results show that different sintering temperature has great influence on the alumina ceramics＇ apparent porosity rate,real density. Besides,different sintering temperature increases grain size and improves pores distribution.It＇s found that the alumina ceramics made in the sintering temperature of 1500 is the best.
