Dielectric Barrier Discharge Plasma Deoxidation of Natively Oxide Layer of Copper Powders in a Fluidized Bed

Advanced Engineering Materials, EarlyView.
This paper presents a novel approach to reducing oxide layers on metal powders using low‐temperature hydrogen dielectric barrier discharge plasmas at atmospheric pressure. Unlike conventional hydrogen‐plasma reductions, the powders do not contact the plasma directly.

Texturing of lead free piezoelectric ceramics

, 2013
Texturing of the lead-free system Ba0.92Ca0.08TiO3 (BCT) was investigated focusing on density, degree of texture and piezoelectric response. BCT templates were prepared in a two-step molten salt synthesis to achieve the anisotropic growth needed for the template morphology.

Development of Sustainable MgO–C Refractories Using MgO–C Recyclates and a Novel Eco‐Friendly Fructose–Tannin Binder Crosslinked With Citric Acid

Advanced Engineering Materials, EarlyView.
This study develops sustainable MgO–C refractories using recycled materials and eco‐friendly fructose–tannin binders. The enhanced performance of citric acid as a cross‐linker and functional additives on mechanical and thermomechanical properties was examined. Characterization included strength tests, immersion trials, and microstructural and inclusion

Texturing of Lead-free Ferroelectric Ceramics

, 2013
The lead-free ferroelectric system 0.75Bi0.5K0.5TiO3-0.25BiFeO3 has been investigated with respect to crystallographic texturing. Recent studies have shown that the system have promising electromechanical properties and may be an alternative for replacing lead zirconate titanate (PZT). Texturing was performed on the system with the aim of enhancing the
