The distribution of iron ions during firing of acid-resistant ceramic materials based on production waste is established using the Mössbauer effect. It is revealed that in samples containing an increased amount of iron oxide (17 – 18%) strength and frost resistance are better than in specimens containing 6 – 7 % Fe2O3. Calculation of the areas of the doublets of the spectrum showed that iron compounds at the surface of the samples studied (where an oxidizing atmosphere predominates) are mainly represented by hematite, and in their central part (reducing atmosphere) by magnetite, and in this case specimen acid resistance is reduced.

基于生产废料的耐酸陶瓷材料中氧化铁的穆斯堡尔谱研究

利用Mössbauer效应确定了基于生产废料的耐酸陶瓷材料在焙烧过程中铁离子的分布。结果表明,在氧化铁含量增加(17 – 18%)的样品中,强度和抗冻性要好于在6 – 7%的Fe 2 O 3中。光谱的二重峰面积的计算表明,所研究样品表面(主要是氧化性气氛)中的铁化合物主要由赤铁矿代表,而在其中心部位(还原性气氛)则由磁铁矿代表,在这种情况下标本的耐酸性降低。
