Effective algorithm for material exploration in ceramics with combinatorial technology

A reaction phase diagram of pseudo-ternary LiO0.5-CrO1.5-TiO2 compounds was established using a fully automatic combinatorial robot system in order to demonstrate the effective application of the combinatorial process. The following crystal structures were obtained by heat treating starting materials at temperatures between 1173 and 1373 K: ramsdellite, spinel, layer, rock salt, corundum, and rutile. The ramsdellite-type compounds in this pseudo-ternary system were obtained rapidly and within a wider composition range than previously reported.
