摘要

本文采用穆斯堡尔谱技术，并结合X荧光、X衍射、中子活化、热分析和化学分析等手段对骊山粘土进行了系统的研究。首先确定了骊山粘土为秦始皇兵马俑的原料来源。继而对骊山粘土进行了同一时间不同温度和同一温度不同时间的试烧，前者分别在氧化和还原气氛下进行，后者仅在氧化气氛中进行。结果表明，烧结18h后各种穆斯堡尔谱参数不再变化。并可望能从样品中非磁性Fe

或Fe

的四极分裂及非磁性强度的分布依赖于试烧温度的变化曲线分别推断出氧化气氛或还原气氛下烧制陶器的烧结温度和烧制时间，估计出秦俑的烧结温度为950—1030℃。

Abstract

Lishan clay has been characterized by Mössbauer spectroscopy

X-ray diffraction

X-ray fluorescence

neutron activation

thermal and chemical analyses. It was proved that Lishan clay was the material used for making the terra-cotta warriors and horses of Qin Dynasty. Firing testing of clay was carried out in various conditions. The transformations induced by firing of clay were characterized by Mössbauer spectra. The data on quadrupole splittings of Fe

or Fe

ions

and on nonmagnetic component distributions at different firing temperatures

may lead to valuable informations on the manufacture of ancient pottery. The sintering temperture for the terra-cotta warriors and horses of Qin Dynasty was thus evaluated to be 950—1030℃.
