项目摘要

The object of this research project is the development of the processing for the in-situ microstructure control of inorganic materials on basis of detailed analyzes of reaction schemes during the materials processing as well as microstructural analyzes of materials at nano-and micro levels.In the solid state reaction processing, the novel methods were developed for the synthesis of morphologically controlled silicon nitride powders by the reaction control of a solid-gas system, and for the microstructure control of sintered bodies with nano-sized particles. A new fluorescence material could be developed by the control of coordination of polyhedrons. The reaction controls in solutions or liquids were found to be the most important key factor to hybridize a sensor structure and nano particles in glass matrix.. The chemical solution processing did contribute to the discovery of a new substance with cage-structure and a development of super high water repellent material. This processing also led to the development of a new system for the micropattering of wave guides and value-added materials.Through the chemical vapor reactions, the microstructure control factors were carefully examined to process the well-designed multi-layred films.These results are expecting to contribute greatly to the materials development with designed microstructures and properties and to the establishment of the materials science and engineering.

本研究项目的目标是在详细分析材料加工过程中的反应方案以及在纳米和微米水平上对材料的微观结构分析的基础上，开发用于无机材料的原位微结构控制的工艺。在固态反应加工中，开发了通过固-气体系的反应控制来合成形态控制的氮化硅粉末的新方法，以及用于具有纳米尺寸颗粒的烧结体的微观结构控制。通过控制多面体的配位，可以开发出一种新的荧光材料。发现溶液或液体中的反应控制是使传感器结构与玻璃基质中的纳米颗粒杂交的最重要的关键因素。化学溶液处理有助于发现笼状结构的新物质和开发超高拒水材料。通过化学气相反应，研究了影响微结构的因素，制备出了具有良好微结构和性能的多层膜，这些结果将对材料科学和工程学的建立，以及微结构和性能设计的材料的开发有重要的意义。
