Morphotropic phase boundary in the BNT–BT–BKT system

Jean-François Trelcat, Christian Courtois, Mohamed Rguiti, Anne Leriche, Paul-Henri Duvigneaud, Tiriana Segato

Lead-free x Bi0.5Na0.5TiO3–y BaTiO3–z Bi0.5K0.5TiO3 piezoelectric ceramics were synthesized by a conventional solid state reaction method. The microstructure, ferroelectric and piezoelectric properties of the ceramics were investigated. Structure measurements by X-ray diffraction with Rietveld…

Influence of temperature on the hydration products of low pH cements

T. T. H. Bach, C. Cau Dit Coumes, Isabelle Pochard, Cyrille Albert-Mercier, B. Revel, André Nonat

The chemical evolution of two hydrated "low pH" binders prepared from binary (60% Portland cement + 40% silica fume) or ternary (37.5% Portland cement +32.5% silica fume + 30% fly-ash) mixtures was characterized over one year at 20 degrees C. 50 degrees C, and 80 degrees C. The main…
