Pre-synthesis of functional grains for manufacturing of ‘Refractory Composites’

该项目的重点是研究用于制造“耐火复合材料”的功能颗粒的预合成。晶粒的预合成是在不同的制造路线和烧结条件下进行的，这些条件会影响晶粒的颗粒几何形状（通过粉碎晶粒形成多面体，通过海藻酸盐路线形成球形，通过3d打印形成可调节形状），表面形貌和化学性质，以及作为陶瓷和金属部件函数的生成粒度分布。一种全新的方法是在特殊的加热显微镜下研究基于项目2的粗粒芯/壳结构的三明治组件的电辅助润湿性，以及基于项目1的3d打印组件的细粒结构。通过在pt电极的帮助下施加电压，将研究三个润湿阶段。

The focus of the project is the investigation of the pre-synthesis of functional grains for the manufacturing of “Refractory Composites”. The pre-synthesis of the grains takes place with the aid of different manufacturing routes and sintering conditions, which influence the particle geometry of the grain (polyhedral via crushed grains, spherical via alginate route, adjustable shape via 3D-printing), the surface morphology and chemistry as well as the generated grainsize distribution as a function of the ceramic and metallic parts. A complete new approach is dealing with the investigation of the electrical assisted wettability in a special heating microscope of sandwich components based on coarse grained core/shell structures of the project 2 as well as fine grained structures based on 3D-printed components of project 1. By applying a voltage with the aid of Pt-electrodes the three wetting stages will be investigated.
