搪瓷烧成温度计算方法

搪瓷釉的烧成过程是一种“液相烧结”过程，其传质有赖于熔体的粘性流动。根据玻璃态物质化学组成-结构-粘度-温度的一般关系，推导出计算瓷釉烧成温度(T烧)的经验公式。     

A Quick Color Test to Detect Lead Release From Glazed Ceramic and Enameled Metalware

Abstract

A color test is presented for the purpose of quickly identifying glazed ceramic and/or enameled metalware which releases excessive Pb. Citric acid solution on filter paper is used to extract Pb from the ware and a Pb-sensitive chromogen indicates the presence of Pb on the paper. The quick color test takes approximately 30 min and is useful for screening ware to determine the need for testing by the 24-h method of the Association of Official Analytical Chemists/American Society for Testing and Materials.     

寿州窑瓷器的测试与初步分析

采用能量色散X射线荧光(EDXRF)技术和热膨胀法对寿州窑瓷器的元素组成和烧成温度进行了测试分析.研究结果表明:寿州窑瓷器的瓷胎具有高铝低硅的特点;瓷釉属于钙釉,寿州窑的青釉和黄釉产品不是由于着色元素的差别引起的,很可能是在不同的烧造氛围中形成的;管咀孜窑口的青釉瓷器烧成温度在1 200℃以上,住院部窑口的黄釉瓷器烧成温度在1 100℃以上,1 200℃左右.

宋代官钧的美学内涵解析

钧台窑作为官窑的历史虽然短暂，但少量传世器物及近年来出土的窑址残器，还是让世人了解了在造型和装饰上趋于完美的钧瓷艺术。宋代官钧的美学内涵和美学价值体现在本真之美、釉质之美、色彩之美和造型、线条之关四个方面。宋代钧瓷在陶瓷史上具有重要的地位，对当世和后世贡献和影响甚大。     

Compositional and technological features of glazed pottery from Aosta Valley (Italy): a SEM–EDS investigation

Twelve finds from archaeological excavations carried out in the Aosta region (Italy) were studied by scanning electron microscopy coupled with energy-dispersive X-ray detection (SEM–EDS). The archaeological samples were shards of glazed pottery dating from the fourth to the seventh century AD. Analysis of ceramic bodies revealed a general homogeneity in composition among the studied samples and the use of a noncalcareous clay for their manufacture; however, two shards stand out due to their high iron contents. Glazes proved to be high-lead products with more than 70% PbO in all of the samples investigated but one. For the latter, a composition poorer in lead and richer in silicon, aluminium and iron was found. SEM observation of the contact region between body and glaze suggests that the vitreous coatings were mostly obtained by applying the glazing components onto the unfired clay body; moreover, a comparison between clay and glaze compositions suggests the use of a lead compound mixed with a silica-rich material, not a lead compound by itself.     

三种典型釉色汝官瓷和钧官瓷原料产地的PIXE分析

选取天青、天蓝、月白色汝官瓷样品27个、钧官瓷样品25个,将这些样品进行质子激发Χ射线荧光分析(PIXE),测定每个样品的化学组分.将所有样品的7种主量化学组成数据进行模糊聚类分析,得到以下结果:对于所分析的样品,其中钧官瓷胎样品的原料产地比较集中,汝官瓷胎的原料产地稍分散一些;多数汝官瓷胎和钧官瓷胎样品的原料产地接近但不相同,个别汝官瓷胎和钧官瓷胎样品有混在一起的情况;汝官瓷釉和钧官瓷釉样品的原料产地和配方明显不同但关系不是很远.     

喷瓷管道用玻璃釉料润湿行为的研究

采用扫描电镜（ＳＥＭ）和Ｘ射线能谱分析（ＥＤＳ）等手段,研究了喷瓷管道用玻璃釉料对碳钢基体的润湿行为。研究结果表明,底釉的润湿面积随着温度的升高和恒温时间的延长而增大,在一定的温度和时间下达到最大值。增加基体表面粗糙度和减小面釉在底釉中的含量,可促进润湿性的改善。基体金属进入界面过渡层以及界面过渡层富集密着剂都有利于釉料润湿基体。
