Grain Growth-Controlled Giant Permittivity in Soft Chemistry CaCu3Ti4O12 Ceramics [PDF]

, 2007
We report a dielectric constant of up to 5.4105 at room temperature and 1 kHz for CaCu3Ti4O12 (CCTO) ceramics, derived from multiphase powders (coprecipitation products), made by a ‘‘chimie douce’’ (coprecipitation) method, and then sintered in air ...

Solid Freeform Fabrication of Functional Silicon Nitride Ceramics by Laminated Object Manufacturing 1 [PDF]

, 2000
The processing of silicon nitride (Si3N4) structural ceramics by Laminated Object Manufacturing (LOM) using ceramic tape preforms was investigated. The key processing stages involved green shape formation (which used the LOM process), followed by the ...

Gel-tape-casting of aluminum nitride ceramics

Journal of Advanced Ceramics, 2017
Aluminum nitride ceramic sheets were formed for the first time by a novel and simple method, namely gel-tape-casting process, where only two additives were used to prepare the slurries. PIBM (a water-soluble copolymer of isobutylene and maleic anhydride)

Composition and luminescence properties of highly robust green-emitting LuAG:Ce/Al2O3 composite phosphor ceramics for high-power solid-state lighting

Journal of Advanced Ceramics, 2023
The major advantage of laser lighting over white light-emitting-diode is the possibility to achieve ultra-high luminance. However, phosphors usually suffer laser-induced luminescence saturation, which limits the peak luminance of laser lighting devices ...

Dual fluorination of polymer electrolyte and conversion-type cathode for high-capacity all-solid-state lithium metal batteries

Nature Communications, 2022
The practical use of all-solid-state batteries is hindered by inadequate cycling performance. Here, the authors propose a fluorination strategy for the positive electrode and polymeric electrolyte to develop all-solid-state Li||FeF3 pouch cells with high

Ceramic methyltrioxorhenium [PDF]

Inorganica Chimica Acta, 2006
The metal oxide polymeric methyltrioxorhenium [(CH3)xReO3] is an unique epresentative of a layered inherent conducting organometallic polymer which adopts the structural motifs of classical perovskites in two dimensions (2D) in form of methyl-deficient, corner-sharing ReO5(CH3) octahedra.
