黄冶窑白瓷的物相和微观结构研究

Study on Phase and Microstructure of the White Porcelain from Huangye Kiln

以黄冶窑四个时期的白瓷样品作为研究对象,利用X射线衍射仪(XRD)和扫描电子显微镜(SEM)对样品进行分析,结果表明:黄冶窑白瓷胎的物相基本相同,主要是莫来石、α石英和方石英、未熔石英和少量的粘土相;黄冶窑白瓷釉中有气泡存在,釉中气泡为圆形,釉中存在微米级的针状或柱状钙长石晶体,釉存在分相结构,且分相结构与析晶相伴而生;黄冶窑白瓷胎中有气孔、未熔的石英颗粒、较大的Ti颗粒、莫来石晶体和石英晶体。

The white porcelain samples of the four periods of Huangye kiln were studied in this paper, and the samples were analyzed by X-ray diffraction（XRD） and scanning electron microscopy（SEM）. The results show that the material phase is basically the same of the white porcelain bodies from Huangye kiln, and mainly mullite,alpha quartz and cristobalite, unmelted quartz and a small amount of clay phase; There are some round bubbles in Huang Ye kiln white porcelain, glazes, so are some feldspathic crystals with micro-level needles or columnar.It is evident to observe phase separation structure, which is accompanied by the birth. Apart from some pores,unfused quartz particles, larger Ti particles, mullite crystals and quartz crystals can also be found in the embryo of Huangye kiln white porcelain.
