摘　　要：以长石、石英、高岭土、石灰石、滑石、氧化铁等为原料,在1240℃-1300℃的烧成温度下制备了铁红微晶釉。在基础釉料配方基础上,采用正交和单因素实验对釉料中氧化铁添加量、烧成温度、保温时间对釉面效果的影响规律及形成机理进行研究。利用XRD、SEM等测试技术对釉层物相组成、显微结构进行表征。结果表明,当釉料配方组成(wt.%)为钾长石26.2%、钠长石11.2%、石英26.2%、高岭土11.2%、石灰石7.4%、滑石5.6%、氧化铁11%-13%,烧成温度为1260℃-1280℃,保温时间在30 min-45 min时,可以获得釉面效果较好的铁红微晶釉。Iron-red microcrystal glaze was prepared at 1240-1300℃,with feldspar,quartz,kaolin,limestone,talc and iron oxide as the raw materials.The effects of content of iron oxide,firing temperature and soaking time on glaze quality and forming mechanism were studied.Phase composition and microstructure of the samples were studied by using XRD and SEM.It was found that iron-red microcrystal glaze with promising quality can be obtained,when the batch formula of the glaze consisted of(wt.%)26.2%potassium feldspar,11.2%sodium feldspar,26.2%quartz,11.2%kaolin,7.4%limestone,5.6%talc and 11-13%iron oxide,with firing temperatures of 1260-1280℃and time durations of 30-45 min.
