Reoptimization of the CaO–FeO–Fe2O3–SiO2 system integrated with EPMA studies (part I—experimental results)

open access: yesJournal of the American Ceramic Society, Volume 108, Issue 9, September 2025.
Abstract New experimental measurements have been obtained for phase equilibria in the CaO–FeO–Fe2O3–SiO2 system at 1250–1740°C for a wide range of oxygen partial pressures (p(O2) = 1, 0.21, 10−5, 10−6, 10−7, 10−8, 10−9 atm) as well as in equilibrium with metallic iron (p(O2) down to 10−12 atm).

Customizable flame‐spheroidized submicron glass particles with controlled CaO–Al2O3–SiO2 compositions

open access: yesJournal of the American Ceramic Society, Volume 108, Issue 9, September 2025.
This study presents a novel flame process for producing customizable CaO–Al2O3–SiO2 glass particles with precise control over size, shape, and composition. By varying flame parameters, submicron spherical particles (0.1–1.0 µm) were successfully synthesized.

Electric field enhancement of ceramics including microdefects

open access: yesJournal of the American Ceramic Society, Volume 108, Issue 9, September 2025.
Abstract In this study, a finite element analysis was performed to evaluate the effect of aspect ratios and dielectric constants of microdefects, such as pores, secondary phases, and grain boundary phases, on the electric field enhancement using the maximum field enhancement factor.
