摘要

本研究的目的是制备并研究具有Aurivillius型结构的Bi5FeTi3O15 (BTFO)陶瓷的晶体结构和相组成。通过热分析和x射线衍射分析对BTFO陶瓷的合成过程进行了研究。采用混合氧化物法和无压烧结法制备陶瓷。在ΔT = 700 ~ 1200℃范围内加热初始粉末氧化物的化学计量混合物时,发现了三个吸热热效应,而在煅烧后加热粉末时,只发现了一个强吸热峰。低温形成的富bi2o3相为基础的中间表面相的熔点形成了弱吸热峰。x射线衍射研究表明,BFTO陶瓷由Bi5FeTi3O15相和Bi4Ti3O12相组成,含量分别为88.3%和11.7%(重量分数)。

Synthesis and structure of Bi5FeTi3O15 ceramics

The aim of the present research was to fabricate and study crystal structure and phase composition of Bi5FeTi3O15 (BTFO) ceramics exhibiting Aurivillius - type structure. By means of simultaneous thermal analysis and X-ray diffraction analysis the process of synthesis of BTFO ceramics has been studied. Mixed oxide method followed by pressureless sintering was used for ceramics preparation. Three endothermic thermal effects have been revealed on heating the stoichiometric mixture of initial powder oxides within the temperature range ΔT = 700-1200°C, while only one strong endothermic peak was found on heating the powder after calcination. The weak endothermic peaks were ascribed to the melting points of intermediate surface phases based on Bi2O3-rich phase formed at low temperature. X-ray diffraction studies have shown that BFTO ceramics consisted of Bi5FeTi3O15 and Bi4Ti3O12 phases in amount of 88.3% and 11.7% (weight fraction), respectively.
