Glass modified barium strontium titanate ceramics for energy storage capacitor at elevated temperatures

Journal of Materiomics, 2019
A glass with composition of B2O3-Bi2O3-SiO2-CaO-BaO-Al2O3-ZrO2 (BBSZ) modified BaxSr1-xTiO3 (BST, x = 0.3 and 0.4) ceramics were prepared by a conventional solid state reaction method abided by a formula of BST + y%BBSZ (y = 0, 2, 4, 7, and 10, in mass).

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Realizing simultaneously excellent energy storage and discharge properties in AgNbO3 based antiferroelectric ceramics via La3+ and Ta5+ co-substitution strategy

Journal of Materiomics, 2023
AgNbO3 based antiferroelectric (AFE) ceramics have large maximum polarization and low remanent polarization, and thus are important candidates for fabricating dielectric capacitors.
