Spark Plasma Sinering Simulation of Alumina Composite Modified with Carbon Nanotubes
Ceramic alumina composites with carbon nanotubes (20 - 50 %vol.) were prepared by spark plasma sintering method. Dependence of the composite strength from porosity and the amount of CNTs was found.

Preparation of binderless SiCw/WC cemented carbides by spark plasma sintering
SiC whiskers (SiCw)/WC binderless cemented carbides were prepared by spark plasma sintering (SPS), using SiCw as the toughening phase. The effects of sintering temperature and SiCw content on the microstructure and properties of the SiCw/WC cemented ...

Nanocrystalline apatites: From powders to biomaterials [PDF]
Non-stoichiometric nanocrystalline apatite powders are used to elaborate highly-bioactive biomaterials. Their exceptional surface reactivity arises from a structured but rather unstable hydrated layer involving ions in nonapatitic chemical environments ...

Hardness and friction behavior of bulk CoAl2O4 and Co–Al2O3 composite layers formed during Spark Plasma Sintering of CoAl2O4 powders [PDF]
Materials made up of a Co–Al2O3 composite coating over a CoAl2O4 core are prepared during Spark Plasma Sintering of CoAl2O4 powders. The Co particles are precipitated because of a combination of high temperature and low O2 partial pressure.

Processing and Characterization of AlN–SiC Composites Obtained by Spark Plasma Sintering
In this paper, the dependence of the microstructure and properties on Spark Plasma Sintering modes of an AlN-35 β-SiC (wt.%) composite is investigated. It was found that the use of a heating rate of 100 °C/min during the sintering process of the AlN-35 β-

Electrophysical Properties of the Multiferroic BFN-Ferrite Composites Obtained by Spark Plasma Sintering and Classical Technology [PDF]
In the paper the multiferroic (ferroelectric-ferromagnetic) composites based on ferroelectromagnetic/ferroelectric (BaFe1/2Nb1/2O3 (BFN)) powder and ferrite powder (zinc-nickel ferrite) were obtained by two technological methods. In the composite samples

Spark Plasma Sintering of Ultracapacitors [PDF]
A solid-state ultracapacitor module to replace standard electrochemical batteries would achieve major performance gains and mass/volume reduction. This report summarizes a project to evaluate an alternative sintering process to produce a solid-state ultracapacitor to overcome the limitations of both the electrochemical batteries presently in use on ...

Assessment of carbon contamination in MgAl2O4 spinel during spark-plasma-sintering (SPS) processing [PDF]
Carbon contamination caused during spark-plasma-sintering (SPS) processing was investigated in the MgAl2O4 spinel by Raman spectroscopy. Although the carbon contamination became remarkable around the sample surfaces directly contacting the carbon paper ...
