摘要
本文用穆斯堡尔谱对天青色现代汝瓷的釉料和胎料样品进行了研究。烧制气氛为还原气氛,根据它们的穆斯堡尔谱得到以下结沦: 1.随着烧制温度的上升,顺磁峰Fe^(2+)/(Fe^(2+)+Fe^(3+))增加,1200℃为80％;磁比率下降,1200℃时为20％。 2.釉料的脱羟基温区较宽,胎料的脱羟基温区较窄,这对保证天青色汝瓷的质量是有益的。 3.天青釉呈色机理与结构铁Fe^(2+)/(Fe^(2+)+Fe^(3+))的比值以及淡蓝色的玻璃态物质FeO·SiO_2中均匀分布着Fe_2O_3和Fe_3O_1小颗粒有关。 4.天青釉在低温区和高温区Fe^(2+)外的配位数为4,中间温区的配位数为6. 5.讨论了天青釉磁性随烧制温度变化的规律。
The firing study is conducted for the glaze and body of the imitative ancient skygreen Ru porcelain by Mssbauer spectroscopy. The firing atmosphere is a reductive atmosphere. The following conclusions are drawn from their Mssbauer spectra: (A) When firing temperature is going up, the ferrous relative intensity Fe^(2+)/(Fe^(2+)+Fe^(3+)) of paramagnetic peak increases, being 80％ at 1200℃. (B) The dehydroxylation temperature range of the glaze is more broad than the body. They are beneficial to ensure the quality of sky-green Ru porcelain. (C) The coloring mechanism of the sky-green glaze are associated with Fe^(2+)/(Fe^(2+)+Fe^(3+)) and the distributed small Fe_2O_3 and Fe_3O_4 particles in the light blue glassy substance of FeO. SiO_2. (D) The coordination number of Fe^(2+) in the sky-green glaze is 4 in low and high temperature range and 6 in the intermediate temperature range.
