The aim of this project is the development of optimized synthesis routes to metastable oxides and oxide nitrides of vanadium, niobium, tantalum, chromium, molybdenum, and tungsten. In addition, we want to obtain a fundamental understanding of the processes during genesis of the metastable phases and their transformation to thermodynamically stable polymorphs. The cooperation of all our groups, working in complementary fields, is of real importance. During the project we intend to optimize the synthesis routes by increasing feedback between in situ characterization, theory, and preparation. Finally, a knowledge-based concept for the synthesis of metastable oxides and oxide nitrides should be developed, leading to novel materials with interesting physical properties.

该项目的目标是开发优化的合成路线，以获得钒、铌、钽、铬、钼和钨的亚稳态氧化物和氧化物氮化物。此外，我们还希望对亚稳相的形成过程及其向热力学稳定晶型的转变有一个基本的了解。我们在互补领域工作的所有团体的合作具有真正的重要性。在项目期间，我们打算通过增加原位表征、理论和制备之间的反馈来优化合成路线。最后，应该开发一个基于知识的概念来合成亚稳态氧化物和氧化物氮化物，从而产生具有有趣物理性能的新型材料。
