摘要

本文介绍了一种用Ce和Sr的醋酸溶液代替目前常用的硝酸盐合成Ce1-xSrxPO4系列陶瓷材料的简单方法。合成方法为Ce1-xSrxPO4(其中x = 0,0.1, 0.2, 0.3, 0.4, 0.5)，在室温下将ce1和Sr()的醋酸溶液与NaH2PO4简单混合。不同烧结温度下，独居石结构中Sr的崩解范围为600?C到1000?C被调查。采用x射线衍射跟踪热处理后相组成的演变。用扫描电子显微镜观察了烧结陶瓷的形貌，用傅里叶变换红外光谱法观察了选定光谱的振动带。评价所选样品的相对几何密度。报道了制备高温铈锶磷酸盐基陶瓷材料的最有利条件。

The influence of strontium content and sintering temperature on monazite stability

This paper shows a simple way to synthesize a series of Ce1-xSrxPO4 ceramic materials using acetate solutions of Ce and Sr instead of nitrate which were used so far. For synthesis, the preparation method was used by simple mixing of acetate solutions of Ceand Sr(, with NaH2PO4 at room temperature, and the studied compositions were Ce1-xSrxPO4 (where x = 0, 0.1, 0.2, 0.3, 0.4, 0.5). The disintegration of Sr in monazite structures in different sintering temperature ranges from 600?C to 1000?C was investigated. The X-ray diffraction was used to track the evolution of the phase composition with thermal treatment. The morphology of sintered ceramics was obtained by scanning electron microscopy and vibrational bands of selected spectra were observed using the FT-IR method. Relative geometric density of selected samples was evaluated. The most favorable conditions for obtaining high-temperature Ce, Sr phosphate-based ceramic material are reported.

期刊介绍： Science of Sintering is a unique journal in the field of science and technology of sintering. Science of Sintering publishes papers on all aspects of theoretical and experimental studies, which can contribute to the better understanding of the behavior of powders and similar materials during consolidation processes. Emphasis is laid on those aspects of the science of materials that are concerned with the thermodynamics, kinetics and mechanism of sintering and related processes. In accordance with the significance of disperse materials for the sintering technology, papers dealing with the question of ultradisperse powders, tribochemical activation and catalysis are also published. Science of Sintering journal is published four times a year. Types of contribution: Original research papers, Review articles, Letters to Editor, Book reviews.
