Transparent Polycrystalline Alumina : Processing, Sintering and Microstructural Analysis

Over the last century, the constant quest to improve the mechanical properties of ceramics has ultimately led to the appearance and production of transparent ceramics. Indeed, microstructural refinement and reduction of the residual porosity after sinterin ...

The effect of processing conditions on the morphology, thermomechanical, dielectric, and piezoelectric properties of P(VDF-TrFE)/BaTiO3 composites

Dragan Damjanovic, Yves Leterrier, Véronique Michaud, Sara Dalle Vacche

In this study (0-3) P(VDF-TrFE)/BaTiO3 composites containing up to 60 vol% of ceramic phase were prepared by solvent casting or compression molding. Their thermomechanical, dielectric, and piezoelectric properties were investigated, and discussed in the li ...

Surface Functionalisation of Alumina Ceramic Foams with Organic Ligands

Sandrine Gerber, Vincent Laporte, Françoise Borcard, Pascal Miéville, Marc Anthony Caporini

Different anchoring groups have been studied with the aim of covalently binding organic linkers to the surface of alumina ceramic foams. The results suggested that a higher degree of functionalisation was achieved with a pyrogallol derivative - as compared ...

Atomistic modeling of dopant segregation in alpha-alumina ceramics: Coverage dependent energy of segregation and nominal dopant solubility

Paul Bowen, Ulrich Aschauer, Sandra Caroline Galmarini, Yann Aman, Abhishek Tewari

Microstructural control is a key aspect in producing ceramics with tailored properties and is often achieved by using dopants in a rather empirical fashion. Atomic scale simulations could provide much needed insight but the long-standing challenge of linki ...

Prototyping a High-Frequency Inductive Magnetic Sensor Using the Nonconventional, Low-Temperature Co-Fired Ceramic Technology for Use in ITER

Thomas Maeder, René Chavan, Jonathan Bryan Lister, Jean-Marc Moret, Gilbert Tonetti, Duccio Testa, Jérôme Guterl, Matthieu Toussaint

The ITER high-frequency (HF) magnetic sensor is currently intended to be a conventional, Mirnov-type, pickup coil, designed to provide measurements of magnetic instabilities with magnitude as low as |dB|~10e-4G at the position of the sensors and up to freq ...

The Effect Of Processing Conditions On The Morphology, Mechanical And Electrical Properties Of Batio3-Polymer Composites

Yves Leterrier, Véronique Michaud, Sara Dalle Vacche

Ferroelectric ceramic – polymer composites have a unique mix of electrical and mechanical properties. Piezoelectric and pyroelectric activity, a wide range of dielectric constants and high breakdown strength are combined with mechanical flexibility, formab ...
