中文名称：耐火材料玻璃和釉的化学分析 用带有1,10-菲罗啉的分光光度法测定Fe2+和Fe3+
英文名称：Chemical analysis of refractory material glass and glazes — Determination of Fe2+ and Fe3+ by the spectral photometric method with 1,10-phenanthroline
发布日期：2011-12
标准范围
This International Standard specifies a spectral photometric method with 1,10-phenanthroline for the quantitative determination of Fe(2+) and Fe(3+) in oxidic raw and basic materials for ceramics, glass and glazes, e.g. feldspar, kaolinites, clay, limestone, quartz refractory materials. This International Standard could be extended to other aluminosilicate materials, providing that uncertainty data is produced to support it. However, there might be problems in the decomposition of high-purity alumina and chrome ore samples.The method is not suitable for reduced materials, such as silicon carbide, graphite-magnesia, etc.
