Intergranular films at metal–ceramic interfaces Part I – interface structure and chemistry
نویسندگان
چکیده
In this work the structure and chemistry of intergranular films at metal–ceramic interfaces was investigated via detailed microstructural characterization of model metal–Al2O3 nanocomposites. We report here experimental results indicating the formation and stability of equilibrium nanometer-thick films at metal–ceramic interfaces. Thin 1 nm interface films were observed for two different metal–alumina systems (Ni and Cu) doped with glass-forming additives. High spatial resolution energy dispersive spectroscopy showed a difference in the chemical composition of the films at Ni–alumina and Cu–alumina interfaces. These results may have immediate ramifications on structural and functional properties of metal–ceramic interfaces. 2004 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.

Nano Dispersed Metal-Ceramic Composite Materials of the Ni-SiO2 system
In the organic field effect transistors (OFETs) generation, the silicon gate oxide is 1-2 nm thick. A shrinking of this thickness down to less than 1 nm for the next generation will led to a couple of orders of magnitude increase in tunnelling as well as leakage currents. NiO-SiO2 can be used in a variety of devices, such as in circuit boards and detectors, including sensors, due to its porous ...

The effects of grain-boundary chemistry on the mechanical properties of high-purity silicon nitride ceramics have been investigated, specifically involving the role of oxygen, present along the grain boundaries, in influencing the fracture behavior. To avoid complications from inadvertently introduced impurities, studies were performed on a high-purity Si3N4 processed using two-step gas-pressur...

The effects of grain-boundary chemistry on the mechanical properties of a high-purity silicon nitride ceramics were investigated, with specific emphasis on the role of oxygen. Variations in the grain-boundary oxygen content, through control of oxidizing heat treatments and sintering additives, was found to result in a transition in fracture mechanism from transgranular to intergranular fracture...
