引言穆斯堡尔效应已被广泛应用于许多科技领域中,其中之一为考古学。根据样品的每一个特征谱,可以获取一些有用的考古学信息,如陶器的原料来源,烧制温度及记年效应,尤其确定古陶的烧制条件是一项很有前途的应用。铁在陶器中是普遍存在的,在烧制过程中铁也必然经受一些物理化学状态的改变。在烧制过程中,粘土一般经历四个阶段的变化,分别为脱去吸附水和结晶水过程(小于40O℃)、脱羟基过程(400—800℃)、玻璃化过程(800—1000℃)和再结晶过程(大于1000℃)。每个过程的谱参数均有明显的差别。
Introduction The Mössbauer effect has been widely used in many fields of science and technology, one of which is archeology. According to each characteristic spectrum of the sample, some useful archaeological information can be obtained, such as the source of the raw materials of the pottery, the firing temperature and the year-of-the-year effect. In particular, the determination of the firing conditions of the ancient pottery is a promising application. Iron is ubiquitous in pottery and iron must also undergo some changes in physical and chemical states during the firing process. During the firing process, the clay generally undergoes four stages of change, which are the process of dewatering and crystallization (less than 40 ° C), the dehydroxylation (400-800 ° C), the vitrification (800-1000 ° C) And the recrystallization process (greater than 1000 ° C). The spectral parameters of each process are significantly different.
