摘　　要：利用溶液前体物组合化学方法研究了La-Ca-Mn-O的相关系。这种合成方法可以完全重现常规固相反应得到的相关系,表明溶液前体物组合化学是一种研究固态相关系的可靠方法。组合化学方法对于提高寻找新型化合物和研究相关系研究效率方面具有重要意义。The phase relationship of La-Ca-Mn-O system has been studied by combinatorial chemistry-technique using solution as the precursor. It has been shown that the samples prepared with this method represent the phase-relationship nicely, which demonstrates that the solution precursor method is a reliable method for the phase-diagram study. This technique may have great potential in automated high-throughput screening for new solid state compounds and in establishing for more complex phase diagrams.
