摘要

Even the exploration of the phase space given by a large number N (N ≤ 61) of components but a limited number q (q ≤ 6) of elements E-i in e.g. metal oxides E-xt(1)E-x2(2)...E-xq(q)O-y is a demanding task and needs a combinatorial approach which, by setting up starting conditions for solid-state reactions, is taking favour of efficient combinatorial functions. Estimations showed that within a single sample prepared by mixing N starting components, the number of local reaction centres (configurations) is exceeding the number of phase systems. A huge amount of about 10(12) starting grains for a sample of one cm(3) provides population of each configuration many times. The distribution for the grain size and the number of grains building up a configuration allow to explore compositional fields in phase diagrams of the order q. The single sample concept (SSC) is particularly of interest for property oriented syntheses, where e.g. magnetic materials are produced in minor quantities. Magnetic chromatography is applied to extract ferromagnetic materials formed by the SSC. A horizontal separator is presented and applied to extract new ferromagnetic Fe-based oxides from SSC reaction mixtures.

E-xq（q）Oy是一项艰巨的任务，需要一种组合方法，该方法通过为固态反应建立起始条件，而倾向于高效的组合功能。估计表明，在通过混合N种起始组分制备的单个样品中，局部反应中心（构型）的数量超过了相系统的数量。一个1厘米（3）的样本中大约有10（12）个起始晶粒的大量提供了每种配置的填充次数。晶粒尺寸的分布和构成构型的晶粒数量允许探索q阶相图中的成分场。单一样本概念（SSC）对于面向属性的合成特别有用，例如磁性材料的产量很少。应用磁性色谱法提取由SSC形成的铁磁材料。提出了一种水平分离器，并将其用于从SSC反应混合物中提取新的铁磁铁基氧化物。
