Dielectric and Electrical Properties of Manganese‐Doped Ag(Nb,Ta)O3 Ceramics Processed With Stearic Acid Additive

International Journal of Applied Ceramic Technology, Volume 23, Issue 4, August 2026.
ABSTRACT Silver niobate tantalate, Ag(Nb,Ta)O3 (ANT), is an antiferroelectric material of interest for high‐energy‐density, high‐efficiency dielectric capacitors. Its development, however, is constrained by two persistent issues: reduction of Ag+ to metallic Ag0 during processing, and high leakage current under applied field.

Effect of Powder Type on Slurries for Additive Manufacturing of Sodium Potassium Niobate Piezoceramics

International Journal of Applied Ceramic Technology, Volume 23, Issue 4, August 2026.
ABSTRACT Due to its enhanced design flexibility, additive manufacturing (AM) is a game‐changing technology for piezoelectric ceramics. Still, to achieve a high‐quality ceramic by AM, slurry preparation is critical. Piezoceramics based on potassium sodium niobate [(K, Na)NbO3] (KNN) are challenging to densify and therefore require extra care during ...

The Influence of Samarium Doping on the Photoelectrochemical (PEC) Activity of SrTiO3 for Solar Water Splitting

Journal of the American Ceramic Society, Volume 109, Issue 8, August 2026.
A systematic investigation of Sm‐doped SrTiO3 synthesized by a solid state route. The donor doping influences the microstructure and electronic structure so that as little as 1.5 mol% Sm could transform bulk SrTiO3 properties. Enhanced photoelectrochemical (PEC) performance of 1.5 mol% Sm relative to SrTiO3 or 5 mol% Sm showed the importance of careful
